    A different opposed piston engine---

    experimental steam engine

    The stainless cylinders could be heavily finned to increase their surface area for transfer of heat..also the two pistons and other reciprocating parts moving in the same direction will create a lot of inertia forces at the end of the stroke, probably would be better set up as a boxer engine...

    Casting Boiler shells?

    I am sure Richard Trevithick used cast (iron) boiler shells with great success and considered them to be stronger than rivetted wrought iron, I don't know about cast copper though other than the fact that casting are usually more brittle. Stew.
