Repurpose an AIO pump? Somehow that spawns images of dropping a Ford Pinto engine into a Corvette or Viper body... yes, it will move.. but you'll soon wish it didn't.
While a pair of puny AIO pumps in series will work.. its just.. i dunno... wrong
If its for proof of concept, then alright.
If it is for "just a few days", then dont, wait the few days till you get the right stuff.
If it is for "jsut a few weeks/months",... then just dont... i doubt its reliable.
But hey, give it a go if you want., lets us know what happens.
Reality is futile, you will be assimilated by (your) perception.
