I was inspired by the Arvus model, let's say I tried to get a useful version of it.
For the similarities:
-it's a Arvus with more armour, that fires not only snap shots, that has a wepon is not in the Arvus Option list and is essentially cheaper compared to the perfos of the Arvus.
-or also a weaker valkyrie, that has not grav shut insertion, no missiles but has deep strike.
-a winged chimera that...
and so on
by the way, I assume that for you the point cost is just fine
