I don't see any reason you can't use that tank as a vacuum plenum. Don't
know how many inches of vacuum you can pull with a shop vac, but the
tank will help with volume.
Valving to take the shop vac out of the loop could be a simple PVC ball
valve from the hardware store. Costs should be reasonable. Used ought to
work just fine if you can find it.
You can tolerate a slight leak here, you just don't want a high
vacuum/low cfm pump trying to suck air back through the shop vac while
it's running.

Some old friends have a business in town (Maier USA) making accessories
for dirt bikes and ATV's, vacuum forming plastic.
It's a trip watching a droopy sheet of plastic turn into an ATV
seatbase/fender in a matter of seconds! Their Thermwood 5 axis gantry
router is pretty neat too...
