Range issues are something to think about, but not an insurmountable obstacle in a diorama.
Build the knocked out KV-1 and have a tank destroyer team inspecting their handywork, or using it as cover as they move against their next target. If they are holding one or two extra (panzerfaust), I think the inference is made that they knocled out the tank. If you are going to use a few figures in the dio, have a team looking for their next target with that one guy that is always curious that is looking into the hole. Or a photographer taking a pic of a guy pointing at a entry point on the turret or hull and holding up a panzerfaust as a sort of trophy to show what he used to knock out the monster. Theatre of the mind.
Years ago, I did a vignette of a sniper standing over a fallen target. The inference was made without having to try and build in scale a 100 meter or more shot. The sniper was holding the helmet of his target with a bullet hole through it. With the rifle in the other hand. Said volumes.
