Should Mattel ever wish go with rooted hair on MOTUC or POP figures, the resources are already there - do a crossover with the Barbie line. Before anyone gets his/her knickers in a twist, take a look at the "Barbie and the Rockers" Ken doll released around the same time as the first MOTU live-action movie - if that face sculpt doesn't look like Dolph Lundgren, I'll eat my Attack Trak!
Historically, the Barbie line has done quite a few highly successful film and pop culture homages. (I think the LOTR package was one of the absolute best.) Would definitely need a re-sculpt on the standard Ken body for He-man though!
