Haven't seen him post recently on BF50+ but you may look for him in some of the other forums to see if he found something he could comfortably ride.
There are diamondframe (DF) riders that give recumbent ('bent) riders grief & vice versa but who cares if you are riding on 2 (or 3) wheels & cruising down the path/road/hwy with the wind in your face & a smile...? Good luck with your search - sorry not to be more help.
