The closest thing I can relate to this is my Tour of Duty in SWG:
In the beginning, you could hybridize. You could literally become whatever you wanted your character to be. My fave (and what my character identified with) was as a Teras Kasi Master and Pikeman. (aka unarmed martial artist/knuckles & polearm)
Now, did that mean that in my 3+ years in SWG I didn't have her master just about every other profession? Nope. I did. And yes, I did it IC.
BUT...
I min/maxed the impact it had on her and her character development.
For example:
She can cook, but not spectacularly.
She can use stimpacks and had some Combat medic-like awareness of healing- but was no physician.
She can dance, but just enough to blend in formal occasions to get close to her mark. Her mastery in instruments became a strong appreciation for certain types of music.
She can image design- well because that is the single BEST way to blend in as an agent.
She had connections to Spynet as a contracted Bounty Hunter- but she wasn't Bothan and didn't have good connections there.
She could do a bit of splicing- to get computer info- but wasn't really a Slicer per se.
She had an understanding of gene splicing- but all her Bioengineered pets were purchased/given to her.
And so on.
So each thing she did in her overall development created an 'aspect' of her- but she was only a true master and skilled at Unarmed and the polearm (specifically the Zabrak traditional zhaboka- or 'crescent staff'). IC wise, she got crap from others because she was completely anti-blaster and hand-held weapons. In a world where THE thing was a blaster or a 'saber, she preferred the 'intimate kill'. Saying that, she COULD use them (IG mastery), but was really really not a fan and not such a great shot. But, had its uses to slow targets down so she could get her hands on 'em!
So... that's how I think of the ability to 'multi-master' things. Max and Min the impact and IC skill... but still keep it as a part of the character.
And avoid the Mary Sue.
Character growth (and interaction) is stymied when you're uber at everything!!
