What I have seen people do is fit a Mainline Warship body onto a Lima Warship chassis. It seems to work. I agree that Mainline drive gear on the Warship can be fragile.
Don't know about the Bachmann although if it does work it is a reasonably smooth chassis. I happen to have the Lima and Bachmann examples but not the Mainline right now.
Happy modelling
