I suspect your asking for 77 length side wings in particular?
No current plans, the bandwidth to get these made is so tough at current that making a new offerings is unlikely. At current we sell everyone we can get made so it would be irresponsible to offer something new that we can't reasonably fulfill on imo. Based on sales volume, a 75/78 troopy variant would come before the 77.
The current bumpers work and fit well on the 77 imo, for those needing additional side protection behind the rear axle, we have other offerings (Kaymar, Gobi, etc).
Yeah. The bumper like the one you offer with 77 length side wings + the door mated swing outs would be a dream bumper to have. I love my kaymar but stopped using the swing outs after going back and forth about them. The good thing it isn't too hard to remove/add them, just kinda messy because of the grease.
