AC System: Piece Together?

[cebra]

I have a factory AC vehicle but the only thing left is the condenser. I need to put AC in but I plan to do a LS Swap next year. I am considering pulling a complete AC system from a LS vehicle and trying to mount in the original box outside the cab and change the pulley to v-belt (for now). Does this seem feasible? My vehicle isn't quite worth spending $1,500 on a Vintage Air System plus I would still need to change at least the pulley when I do a swap. My heating core, blower motor, gaskets, cables etc are all new as well. Any other potential cheap(ish) solutions to get AC now and require minimal cost when doing the swap would be appreciated?
