He could get the same 100% Auto-Evade of Projectiles (handy against Unblockable SP nodes) that his Classic version has. I doubt they could give either of the DD's extra strength on their attack (how hard can a blind guy hit ?), but that is something that holds them back as well.

They can play into his abilities; most of which revolve around his hyperawareness and reflexes. Every perfect block or dex can give him some sort of charge, buff, etc. This would make him pretty fun to play actually, like a mix of Cap and Nightcrawler.
