A idea to make tank riding more useful and worth the micro tax

What if tank riding worked the same way as open top infantry transport vehicles, like shooting from the vehicle while not getting a movement penalty and instead of disembarking when vehicle gets shot they stay at the vehicle and if the tank gets blown up they die also. similar to infantry halftracks (like having a chance of dying after the vehicle exploded) The game engine have the possibility to support this change and it would both make game more engaging and realistic. This would also be balanced because even if you put a 6 man panzergren to 250 only 3 of the models can shoot , a similar fashion could also work and maybe only 2-4 models should be able to shoot from the tank offering extra dps but not as much as efficient dps as disembarking.
