The seatstays on a recumbent don't have to be an integral part of the frame. Instead you can bolt them onto the dropouts or tabs on the chainstays if there's enough metal there to provide strength. On many bents, the primary job of the seatstays is to support the seat and adjust seat angle, and they don't contribute much to frame rigidity. BUT, it really depends on your frame design.
