[raketenjagdpanzer]

Let's say you have various and sundry parts laying around, and an operable museum-grade M3 Stuart light tank you'd like to turn into an armored reconnaissance vehicle.

Could you put a Bushmaster 25mm gun in the turret (along with ammo feed, etc)?

IR driving lights and upgraded radios are a must, too.

Applique armor (face-hardened whatever local steel you could get your hands on)?

re-engined with maybe a continental diesel scavenged from a bus or large truck?

Maybe even an M175 mount?
