Would appreciate help from the experts. Is this scene feasible?

It's never a good idea to mix early-war and late-war vehicles; even if it's theoretically possible, you wind up with endless critiques and naysayers who say "You'd never see that!"....

My idea would be instead of trying to cobble together a large dio from what disparate elements you have, why not just go for a medium or small dio that is effective with either one, or possibly two definitely-compatible vehicles? The panther F in rubble would look great--but not if you positioned it as if the barrel broke through the wall. Tankers in WWII didn't really do that-- it seriously knocked their guns out of true, and rendered them essentially useless.

One of the best ways to get multiple vehicles together is to model a cross roads.  The "moving" road will cause a back-up on the "stopped" road.  Stopped vehicles can have close proximity (if to the vexations of feldweble, sergeants, the world over).  Which also allows for a lot of casual folk loitering about the vehicles.

However, cross roads are also not where one wants to dig in weapons, except, perhaps, the odd MG, and those really ought to be a few hundred meters off, with tables of fire to support/defend the cross roads.  An AT weapon ought to be well back down either road axis, this better uses the geometry of the mount to secure the road in question.

I realize that is not very "verlinden" of me; but I've spent too much time among redlegs to not view a 7000kg weapon "magicked" 1.5m down into a ruined basement with a blocking building 180º to one side, and a one-block sight line, just more than a bit askance.
