Even if the injuries can't be healed, we aren't actually out of the fight just yet. There is almost literally nothing left for us to do in Gensokyo that we can do that no one else can't, but we can always continue to poke around the dreamworld. Hopefully injuries don't transfer over there.
Not that I can think of anything else to do. We have jack on leads, and Yukari could finish everything without input from us.
EDIT: Actually, I take that back. The one thing we know we could probably due is set dream Konngara or someone else up as the successor on Sanae's end. That should satisify Yukari's desire to have another successor on hand.
