That was a 8x8. I am looking for tracked.
Less a drive for it. The main reason to telescope auto cannons rounds is size. I mean the South Korean K21 And CV9040 both use Bufors rounds they pack a punch but they trade off ready ammo. The British/French 40 CTA round being cases telescoped for more ammo in the turret.

Wouldn't they merely adapt the turret to the tracked chassis?
And plus we've seen a similar tracked vehicle prototype:
