Synthesist Summoner = Ben 10?

[undrhil]

I was reading through Ultimate Magic and I realized that the Synthesist archetype for the Summoner class appears to be Ben 10. When he calls him Eidelon, that's him activating his Omnitrix (or Ultimatrix, depending on the Eidelon he's currently employing.) But that leads me to my question: Can the Eideolon be completely rebuilt when the Summoner levels up or are there restrictions on removing Evolution points, etc?

For instance, let's say I have Ben at level 1 with Humongousaur as his Eidelon. At level 2, he adds Bonus STR. At level 3, he adds Reach. At level 4, can he dump reach and Bonus STR in order to get Extra Limbs (Arms) and another Slam attack (to start using Four-arms) or is he stuck with Humongousaur?

Other ideas for Eidelons to work with the Ben 10 idea:

A quadrapedal pincer with some kind of lightning powers. (Brainstorm)
A biped grabber with Claws and a Slam attack. (Wrath)
A amphibian with a bite attack and some kind of lightning powers. (Lockjaw)

Anyone wanna try to work with this? I'm still new to the system, but it looks like it would work. And the Synthesist Summoner is key because the Eidelon "envelopes" the Summoner. Based on the description, it's more like Ben Ten-thousand's "Ultimate Ben 10" form but I don't see why I couldn't fluff it so the Eidelon appears completely solid while being used....

You can only due an overhaul of your appearance when you gain a new level or use the transmogrify spell I think. Level yes, spell tentative yes.

This might be a series you've never read, but reading what you wrote made me think of Ben Boxer, the mutant from the Kamandi comic book series from the 70's.

He would put his hand on his "cyclotron" heart, and transform into a literal man of steel (like Colossus).

Just made be think of it since you mentioned the name Ben.

Kamandi was awesome! I have a similar character concept but i want to do Mary Marvel instead of Ben 10.

According to Paizo rules, you can change your eidolon's evolutions when you advance in level or with the Transmogrify spell, as said. You can't change your eidolon's base form, though, unless you're an Evolutionist. Synthetist + Evolutionist wouldn't be permitted in Raw (too bad). But there's an evolution in SGG's Extra Evolution permitting that.
Now what I'd need should be only unliving objects base forms and a reduce self evolution, and I could make the ultimate shapechanger as a Synthetist... oh, well.
