We have discussed similar approaches for a biprop engine. A copper inner liner should be fine, assuming it's coated with a very adherent coating within the cooling passages, such as Nickel. Nickel *should* be nonreactive enough to work at moderate temperatures, but we haven't tried this yet. I don't know if Tin would be adherent enough for this purpose.
