I would really want to see this happen. There's also great potential for decent renditions of the heroes' secret identities in proper form, which HT and others did well.
I have some of the 12" articulated Kenner/Hasbro DC animated figures and only a couple IMO aesthetically survived the translation, particularly Robin, Nightwing and Joker, but Batman and Superman really suffered.
Seeing how some anime characters are being nicely done by HT, Medicom and others, I think the DC line can be done. The body would need to be uniquely produced, and what would be the clincher is engineering the articulation to be optimally functional while maintaining good form, such as the joints smoothly closing flushed under the fabric while in a standard, standing pose. This would be a significant developmental leap from the Kenner figures.
Isn't HT doing a Disney line or some other cartoon property? That is an indicator of a brand that is capable and dedicated to developing bodies and costuming to pull this off, and because it's likely the boutique brands that can justify the higher production costs. Given those factors, though, DC Direct theoretically should be able to offer these, but they seem to want larger production numbers and therefore figures with less production value.
