Here are some 200X variants I'm interested in to give Mattel an idea of what at least ONE customer wanting some 200X variants is interested in:
3-5 NEW parts: Egyptian head dress, two-piece Egyptian dress and MAYBE wings (Angella's wings might work).
Re-used parts: Female buck 2.0, Female 1.0 hips, Teela boots and arms, repainted Sorceress staff and Zoar in 200X colours
200X King Hiss
6 NEW parts: Egyptian head, lower arm/bracelets, sandal feet. More imposing snake form with MORE snakes (new snake form has 80's repaint potential and it's a VERY small detail).
Re-used parts: King Hiss chest/shoulders/upper arms/legs, Chief Carnivus loin cloth, He-Ro boot shins. Same staff repainted in 200X colours.
3 NEW parts: 200X robot head (serious looking), removable chest armour and MAYBE a new arm attachment (which can be repainted a bunch of different ways for the other arm attachment figures and put in Weapons Paks)
Re-Used: all of Roboto 1.0 (except the head). Repaint in 200X toy colours.
2-3 NEW parts: two piece dress and MAYBE the 200X robotic Screech
Re-Used: female buck 2.0, female hips 1.0, Evil-Lyn's long and short wand and orb, helmet head and maybe the knife. For Screech everything is Screech 1.0 except the head part. One side of the head + the opposite upper leg = robotic. The foot can just be repainted instead of a new sculpt. No re-use potential I can see).
1 NEW part: tiara head
Re-Used: Grizzlor 1.0 minus vintage head. Weapons = repainted crossbow and maybe some different, already sculpted weapons repainted.
