If I was to redo the Warlock - and I won't, mapping takes months for capships - I'd keep the basic shape and overlay detail. Like recess in those fighterbay doors for a proper launch bay, add proper engines, and make the 'bridge' type section somewhat akin to a mini-city (to provide an offset of scale). It would probably be possible to contrast the large, flat areas by simply adding detail to the appropriate small sections, like distinct recesses, gun platforms and soforth. I'd definately add a couple of trenches where that screwed up girder texture currently resides, too.
That given, I'm not a fan of the simplistic extruded hexagonal tube design that the Warlock opitimizes. I think it's a horribly dull basis for a model, for one thing.
EDIT; actually, there may be a 2nd or 3rd generation Warlock mesh knocking about somewhere in the modeldumps. I can't remember if it was any good; almost certainly would be pre HTL.
