There's already a HD version, it's a lot of rocks and pretty skins for Axis tanks. It even supports SLI/CF!
What I really want is to update some mechanics (greater tactical map controls, unit summary top-right, units-building top-right, reverse button). Ideally truesight would be put in, but I fear all the ray casting will be computationally expensive, as with all the snow tessellation that makes it a nightmare to run on budget rigs.
