In no particular order, just throwing thoughts around for discussion before solidifying my singular choice:
Methodology: Go through the sculpts on Camospecs and find candidates that have...
a) not been resculpted already
b) not reseen
c) not terribly recent
d) the big one: popular enough choices that IWM would turn a profit from resculpting
e) examples of ugly sculpts where _some art is avaliable_ that is not so ugly. If the 'Mech is ugly in art, it'll be ugly in mini - nothing a sculptor can do about that besides make the questionable choice of applying artistic licsense to come up with a derivative work.
Here goes
1: BNC-3S Banshee: Not really a resculpt, but rather a return to representation. Obviously the previous sculpt is problematic to use, for understandable reasons. Still, the S-series Banshees are quite popular choices for Lyrans that don't buy into Atlas hype.
2: Black Lanner in CCG art: Because I can wish and hope to hearts content.
3: Bushwacker: Mini is already alright I suppose, just seems small compared to scale creep'd minis these days. Dated mini too. Given the popularity, might be worth looking at re-sculpting, maybe a new variant?
4: Fafnir: Don't know how popular this one is, but there seems to be a greater acceptance for MW4-eque art in recent times(latest Templar model, for example). I think a MW4-eque Fafnir might be a hit.
5: Falconer: Given how popular this model is, a resculpt to better follow the 3055u Plog art might be worthwhile. Current sculpt is bearable to my eye, though. A sculpt based on the 3055u art would make me a Falconer owner for sure.
6: Glass Spider: The frequency I see people cheesing it up with this thing is in spite of the mini. They took some okay art and simplified the torso to the point where it lost it's character. While I think this may count as a reseen, it's probably departed that field enough to be worth considering.
7: Gallowglas: Specifically, a 3055-ized Gallowglas. Aw hell yeah. Beefier, better details, modernized.
8: Grand Crusader: Despite a fantastic effort by the artist to do better than the art, the mini is still ugly. But that artist succeeded, since the mini looks better than the source art. New art was never released as far as I can tell. Therefore this is excempt from the list. Still, I and others I've heard have strong enough opinions about this form that I had to at least mention it.
9: Gunslinger: The 3055u art is pretty awesome, and the 3050-based mini, while okay for where it came from, wouldn't hold a candle to a 3055u version. In fact, that probably goes for all the 3055u art.
10: Highlander: That mini just looks dated. A lot of people prefer to use the HGN-IIC, which says a lot.
11: Missed this one. 3055u Cerberus.
