Flexible Adept Options

[Voran]

So I started fiddling with this idea back in 3 and 4, though never really got far with it. I was wondering if it might be balanced/plausible/worthwhile in this version. Honestly I'm not sure if this already got covered in a sourcebook/supplement, so I'd appreciate the redirect if so.

Basically I had the idea of a Flexible Adept pool for a physical adept instead of a static array of powers bought. The cost of this flexibility would be an effective 'reduction' of your points available for use at 1 time. You could choose to have static/permanent choices mixed with your flexible pool. In concept, its like the Legion of Superheroes Ultra Boy, who has kryptonian array of abilities but only like 1 at a time.

I'm not sure what would be the best way to manage it, somewhere between, 'pick a number of magic points/powerpoints' you wish to direct to the pool and halve it, giving you the number of pp you have floating to use for powers at any given time. So like 2 points means you have 1 PP of 'whatever' that you can spend as you will to manifest whatever abilities up to the cost as if you bought it. Probably something of Karma expenditure to 'learn' a new ability to add to the rotation, so you don't immediately get access to all Adept powers.

So at 3 pts you get 1.5, 4 you get 2, etc. You could dump all 6 of your initial points into a variable pool of 3, or something. So in comparison to a static adept, at baseline you'd not be able to buy boosted reflexes (magic) rating 3, since that costs 3.5 points...and you only have '3'.

Too much? Not useful enough? Too much of a pain? Thoughts?
