When I mentioned a 105 and era, I sketched a mock up that looked a lot like that. After retirement, this is how most of our M551's ended up. D.co (my company) pulled the last active duty training mission with the Sheridan at JRTC, then turned them in to the post to be turned into vizmods (visually modified) and left at Ft. Polk.
Usually when we did opfor at Ft. Bragg, the only visual changes would be to tape a red star on the turret.
I bet with a lighter Bradley turret, the Sheridan would have been even more agile. It was already pretty nimble for an older generation vehicle. Plus, the smaller size might actually make it more effective at recon than the Bradley.
