With caveats regarding lubrication and wear, yes it would, but you'd
be better off looking at a piece of Meehanite or close-grained cast
iron if you could. Machines better, wears better and has the
self-lubricated properties which are desirable in a piston. 

Self-lubricating does NOT mean it runs without oil!! :-))

If it is a low speed engine then CI is fine, but for anything faster
you should consider Ali as the inertial forces on the small end and
big end get horribly large as the speed increases, I haven't got the
formulae here at work, but it is something like the forces squared for
a doubling of engine rpm.
