OK, super obscure territory here.
Everybody knows I love the Armada designs and want to see more Armada updates in the Generations line. And I'm sure everyone remembers how awesome Armada Scavenger's design is (his toy less so).
What I really want though is an Energon Treadbolt that's an entirely separate mold from a hypothetical new Armada Scavenger.
"But Delta!" I hear you cry. "Why would you want a no-name redeco to get its own mold?"
Because, my friend, said no-name redeco actually got a personality via Ask Vector Prime...and is technically a girl now. And fairly obviously, a straight redeco of a hypothetical updated Scavenger would not make a very convincing girl. Also I'm of the opinion that the more new molds the better.
"But Delta!" again you cry. "How would you get a traditional fembot out of a bulldozer without major shellforming?"
Simple: Don't make her a traditional fembot. Whilst obviously the "Male toy with a female headsculpt" approach is exactly the wrong way to do it, there's more than one obviously feminine body type out there.
So for example, you could make her a burly Amazonian beauty...
Or a more voluptuous, "curvy in all the right places" girl...
(Finding safe-for-work images was NOT easy...good grief.)
But anyway, you get my point. Personally I'd kill for a cuddly construction cutie or a strong structural soldier sister, but that's just me.
Of course we'll never get this because the chances of Hasbro investing that much money/effort in a character who only gets any fiction at all thanks to AVP are slimmer than Legends Blackarachnia's waist. Also, even if they did do it, if they went with the plump design you'd have the usual suspects whining that they didn't make her morbidly obese and would accuse the designers of "thin privilege" or some such garbage.
