I think these would be VERY interesting, but VERY difficult! To get the screens to look right would take quite a careful bit of casting. There are also a LOT of struts, etc inside the screens, plus the propellers and their drives. To be done well this would require so much hand assembly that it would properly be in the realm of Strictly Limited and/or Honour Bound.
Another choice would be US or British? Each country had variations. The US versions were all built on cast hull M4A1, the British built theirs on Sherman III (M4A2) and Sherman V (M4A4). Each country used a different idler and a few detail differences. Fortunately one or two British units used US-built M4A1DD's for Opn Overlord.
Other DD details: The commander had a small platform on the rear of the turret. He stood on this so he could see over the screens and steer the tank. The had a tiller that was linked to the props. The US version (at least) had the headlights extended upwards for use over the folded screen, and the headlight brush guards were extended as well. The idler wheels were actually sprocket hubs - in fact the Brish versions had sprocket teeth fixed in place on the idler.
American DD tanks were also used in Opn Dragoon (Southern France) and in crossing the Rhine. The British used theirs again for the Rhine operations.
A model of these would be a kicker, but quite difficult to do well. That's why no plastic models of these have been released (yet).
