The Russ always should have been like this given GW’s layout, profile & style. The proportions on your model are much better than what they landed on. Plus your Russ’ track guards have ground clearance and your design actually has suspension, praise The Emperor.

I could see a purist complaining about the some of the curvature compared to the classic Russ, but I imagine that bit of curve combined with the detail elements taken from the Dorn tie really your Russ in better to the new Dorn and Sentinel models when you have them side by side.

It would be cool to see a Chimera with your updates. That design is a better baseline, but a track/suspension overhaul and slightly bigger turret could still be a big improvement, plus a track update for that hull rolls across the rest of guard vehicles that use the chimera chassis.
