The rules make no statement other than "must require 2 sets" so, yes, you can use other equipment. As ever, though, the harder it is to acquire said equipment, the less likely a game will be played (a basic limitation any game suffers, IGDC or not). In general, if the rules do not assert a restriction, you may presume no restriction.
