I wonder if there could be a Strike It Lucky/Rich revivial, or of it's too assosiated with Barrymore and his reputation (not that it's stopped Challenge repeating it for years).

It was used on Epic Gameshow, so they've tried. It's odd that none of the shows used on Epic were spun off into full revivals - the Vernon Kay version of Family Fortunes came about after it was used on Gameshow Marathon, and Bullseye also got revived by Challenge off the back of that.
