[@KoL]: I'm gonna say no on that simply because it creates far too many issues to deal with on a case-by-case basis. The biggest issue, of course, is that there's no way to differentiate 'real' from 'game', but there's also character reasons... Namely, the fact that Hans without his NP is super dead weight (and it basically means you'd be sacrificing him for your own character to get that stuff). Y'know, cuz that's just how that NP works. There's also the issue of writer's block and all the associated issues (like learning the personality of that person, buffing a person for no good reason, etc;).

Lotsa reasons as to why that prob ain't gonna fly.
