Yet another question about Rogue Talent: Ki Pool

[Arkhios]

So...

Let's say I make a ninja, and take the Rogue Talent for Ki Pool instead the normal Ninja Trick (because according to RAW, I can)

Does this choice qualify for me to decide whether I want to use my character's wisdom or charisma as the ability for the Ki Pool to draw power from, without actually multi-classing to another class?

If so, and if I chose Wisdom, would I also get the bonus Ki points per half my Wisdom modifier, in addition to the normal points granted by Wisdom in the first place, due to what it says in the Talent about having a ki pool already or getting one later?

Logically I wouldn't see a problem in this. This would basically make the said talent work like a talent for bonus ki points. But likewise, logically wood should be burnt by fire, yet it doesn't in D&D because Hardness prevents it... Anyway, what I mean is that logic rarely meets the Rules As Written (especially in D&D and its derivatives), and I wonder if this option would make an exception to that?

" ...If she already has a ki pool, or gains a ki pool later, she gains half her Wisdom bonus (minimum 1) as bonus ki points to her ki pool. She can spend a ki point to gain a +10-foot bonus to movement until the end of her turn."

If you already have a ki pool, this talent won't change the way it works, it'll just give you the bonus ki points and the movement bonus ability.
You would acquire your normal Ninja Ki pool using Charisma, and then add the bonus points based on Wisdom.

so unless you have a +4 for your wisdom bonus (which would give you 2 ki points) you would better off NOT burning your ninja talent on the rogue's version of ki pool and just take a combat feat, then use your next feat to take Extra Ki feat netting you the same amount (and it can be taken multiple times if you are going to need that much ki a day)
