96 Caravan 3 l oil pan gasket replacement

I just tightened the very loose bolts on my leaking oil pan, and the leaks
are now much worse. Haynes says that to replace the gasket, the exhaust
pipe must be disconnected, all mounts removed, and the engine on hoist from
above to get access to some of the bolts. Is there any way to replace the
gasket without this much work? No doubt the exhaust studs will break, the
mount bolts will be seized, and I'd need to rent a portable lift. Anyone
found another way to reseal the pan?

Thks.
