It's not out of the realm of possibility to get a new AT-ST some day...
It's a relatively small vehicle (especially for Star Wars), and thus its scale wouldn't be absurd.
I agree the original sculpt is looking dated... I'd take one with a joint at each point on the leg that it should have, an opening 2-seater cabin, and complete accuracy. The viewports would open as would the top hatch, the gun turrets (And grenade turret) would tilt up and down, and the head would turn left/right...
I'd dump the "walking" feature all together though, for poseable legs/feet instead (with good/stiff joints).
To-scale with an accurate ROTJ paint job...
The modern version suffers from a few major issues besides being underscaled. Namely it's based on the design of AT-ST's in ESB as opposed to those of ROTJ which are much closer/easier to make out. Of course one could always say the ESB version's a different "type" of AT-ST all together.
We got a scale landspeeder out of left field, so I hold hope someday a new AT-ST floats out. I'd buy at least SIX of the things (Standard flanking formation for an AT-AT). **wink wink**
