The way priority character generation compares to karma advancement means that this character is pretty much hamstrung your future advancements compared to one who specializes first and then adds versatility to their with karma. Also the implied anti-ware stance means no advancement over there either, and little to no meaningful way to spend nuyen.
It's a novel idea, but I don't think this character will be very enjoyable in play. For seven rolls a week he can whip up the dicepool of a specialist (sans ware & magic), and the rest of the time he won't be able to hit challenging thresholds. His team may percieve him as a burden, and the GM will struggle to provide opportunities to use more than a small fraction of those two dozen skills. Forget about extended tests, and with an initiative of 6+d6, and an attacking dicepool of no more than 7 or 8 even with the most desireable situational modifiers, forget about meaningful contribution in combat.
PS: Why take group bio-tech on an anti-transhumanist?
PSS: Shinobi, while the adept suggestion might add some viability to the concept (and the priority B human), not being awakened seems to be explicitly part of the plan here.
