It should be possible to just grab the names of the new scripts (.scr files) and whack them in a .mct file. There might be a few keyed to terrain that doesn't show up on the default maps (I don't know if any do or not), but other than that it should work fine.
I won't have a chance until Wednesday (gotta run now), but if no one has done it by then just give this thread a bump Wednesday morning to remind me and I'll put some SP campaign files together.
