Should work great. Probably need to shorten the chain if it's in the original length intended for a 52/40 chain ring combo.
Set it up with the new chain rings and see if the chain looks saggy on the small/small combo. If so, take out a link pair and check it again. Still saggy? Take out another link pair. Even if you rarely use the small/small combo, it should be useable. With such a small difference up front, this should be easy-peasy.
