Swap decks on a Husqvarna?

Is it possible to swap a 54" deck on my YTH2454 for a, say, 42" deck from a Husqy, Craftsman, Poulan, etc...? I have some reasons to have two different blade setups for my business, and would like to use the YTH as a dual-unit depending on the workload. If I find a 42" or 46" deck, can I simply drop the 54" and belt up the 42"?

TIA!
