can I make my jeep electric fan run two speed with a volvo relay?

[superwade57]

So I have an electric fan from a 02 jeep grand cherokee, I believe this is a single speed fan. I also see its very common to run a factory fan relay from many volvos, they are two speed, extremely durable, and plentiful, which makes them affordable. Combine that with a single, dual temp, switch from a BMW makes a pretty bullet-proof and affordable and clean electric fan setup. My question is can I convert my single speed jeep fan to a dual speed fan using common parts and reliable techniques? I'll flush mount the jeep fan into my factory shroud, and I'm running a 355 with a large 4 core rad from a 454 suburban. I'm combining this mod with a serpentine conversion from an 89 Camaro so I'll already have the upgraded the Alt.
