To do this properly aft view should probably also be flipped upside down (as if you were standing on your head when looking behind you). That way 1) cycling over all the views front-top-aft-bottom-front will give you consistant change, just like doing it laterally front-port-aft-starboard-front does it now and 2) the up/down controls stay the same over all four views whereas yaw/roll axes stay the same for front/aft views and are simply exchanged for top/down views.
There are OXP ships that do some nice things with custom views like gun/scoop/cargo views in Thargoid's Vortex, but yet I didn't see OXPs fiddling with view/weapon positions.
What do you think would it be practical/useful thing to do? Or have I overlooked something obvious? I probably won't have the time to do and playtest it this week (well, actually I probably should to learn quite a bit more about quaternions first
