Worth the trouble?

I say no, just get with Hughes and get yourself a cam thatll work with what you have. New pistons is a new balance (if not stock weight) and the 360 stuff is all balanced together. That price and pistons, gaskets, yadda yadda. Might as well get a running stock 440 and drop in more than what you have. JMHO. Hope you reach what your looking for however you arrive at it. :-)
