Have you tried the DBS? What you said seems to fit the description of the DBS....
The DBS/DBX don't got the right canopy; you can't see below you. They're fun ships, but don't provide the all-round Asp view unfortunately. I haven't G5'd an Asp Scout yet (it's my last ship to engineer aside from Cobra mk IV), I know it's more nimble than an AspX, but it didn't seem as maneuverable and fast as the smaller ships. It has the canopy though, and I'll be testing it out for fun-ness.
I honestly have no delusions that my high-end small-with-a-huge-hardpoint will ever be in the game (I mention it only as a fantasy and not something to be expected or feasible), but I do think a Viper level ship with much better visibility could work.
