I definitely have to say I agree re: the Borg eye, having the Borg in the MU is a whole can of worms that is very difficult to reconcile. Their origin in the "real" universe, in regards to the Alpha quad anyway, is essentially due to Q. Now if Q cared to dally about in the MU considering his origin I doubt the Terran Empire humans would have survived the "dangerous, savage child-race" trial. But blah blah blah geek geek geek, I digress.
The regular eye patch looks a lot better than the implant. But may I suggest that if Will is destined to be a Cyclops you might go a route that's more fearsome and deliberate appearing, like a big scar cutting through a clouded eye. The patch seems a bit anachronistic and almost a sign of weakness emphasizing a disability, whereas something more vicious and on display would serve as far more unnerving warning to anyone choosing to mess with the captain of the I.S.S. Titan.
