Would you really want to fight against a 75 fuel tank that can fire at infantry from 50 range and switch shells to fight vehicles though? It would become somewhat like the old M-42. A blob of them is cheap and they're quite beefy and hard to hit, so if they'd have AT shells you'd have no cost effective way to counter them.
I'd say keep any buff focused on their primary role to keep the counters clear and prevent balance issues.
A direct fire MOD with low performance that allow them to fire back vs light would not be bad. Could do 80 damage similar to KV8's gun.
