Character is an arcane bloodline sorcerer.
Crossblooded evolution lets him add a divine spell to his spell repertoire. Say Heal. He now has heal in his spell repertoire and he can cast heal "as a spell from [his] arcane tradition." So he casts heal as though it was an arcane spell.
Arcane evolution lets him add all the spells that he has in his repertoire to his spell book. So he adds heal, as an arcane spell, to his spell book.
The heal spell, which he learned through crossblooded evolution, can be swapped out of his repertoire "as you could any other sorcerer spell."
The section on swapping spells in the repertoire says that a sorcerer can use retraining during downtime to swap out the spells in his repertoire. So this includes the spell added using crossblooded evolution.
He retrains, removing heal from his repertoire and replacing it with any other spell from any other tradition. Say, neutralize poison.
Heal is no longer in his standard repertoire. But it is still in his spellbook, as an arcane spell. Arcane evolution lets him add heal to his spell repertoire for the day.
He also now knows neutralize poison, treating it as an arcane spell, so he adds that to his spellbook too.
Retrain neutralize poison to some other spell, and repeat.
Given enough retraining time, he can add every spell, of every tradition, to his spell book treating them all like arcane spells.
So using arcane evolution, the character can pick any one spell, from any tradition, to be one his known spells for the day. And he can change which spell that is every day.
Thoughts?

I think it sounds an awful lot like that Sorcerer is sitting at home Retraining endlessly while his buddies are out adventuring, and not gaining that much of an extra benefit.

This would take the PC in question literal years to accomplish after having adventured enough to level up to gain those feats.
I would most likely say that during the four or so decades worth of downtime this would require the PC tragically dies in a house fire caused by falling asleep on their desk while burning the midnight oil. All of their work and their body is destroyed in the accident. Easy peasy, I could finish that character's story arc within about 5 minutes at the table and ask the player to roll a new PC.
:D

Hypothetically "oh my gosh, that's too good to allow"
Practically "yeah, sure, sounds fine. Glad you've got a plan what to do with whatever downtime you happen to have during the campaign."
I don't even care that it is weasel-like in nature, the effect just isn't that likely to have much of an impact when taken out of the "got every spell I want" white room and put into the terms of a real campaign (which almost always means not getting exactly as much downtime as you want exactly when you want to have it).

I thought at least one of the feats of that nature has a clause that if it stops being in your repertoire it disappears from your spellbook. Trying to find which variant is it and see how the wording is different. Thought it might have been the bard one, but I'm not seeing the wording on AoN. Will need to check CRB to see if AoN missed some clauses.

What's the point of being an arcane spell caster if you're not going to be a weasel?
More realistically, I'd use this to add a small selection of the most useful non-arcane spells to my spell book. I wouldn't need to take the time to add them all.
In the same amount of time that would be required to craft a really nice new staff you could instead add three or four highly useful spells to your spell book.
I don't think the idea that the spell you understood perfectly last week suddenly becomes gibberish because you studied something else makes much logical sense. But then I suppose it is magic, and the GM could simply justify it with a don't be a weasel sort of logic.
As a GM I would put this on my recurring villain Lich so that he always has the spells he needs for all situations. And presumably he's got the time to learn all these spells before he meets the PCs.

RAW, I don't think it works. The ability to cast the spell as part of another tradition is part of Crossblooded Evolution. If you don't have CBE for Heal, you don't have the ability to use Heal as a divine spell. The act of transcribing it into a spellbook, as far as I can tell, doesn't really have anything to suggest it creates a 'permanent' arcane version of the spell.

Pathfinder retraining is always like that - last week you could do something, but now you can't. If you've been using that something regularly, then it's probably not going to feel very realistic.

Good point. That is very true. Retraining in general does massively stretch character development realism.
"What do you mean you forgot how to speak a language that you knew flawlessly last week!?"
