Well, the problem with this game is, that it doesn't use any development environment that is available on MOS also (like SDL). So a port of this program would mean to do a lot of work concerning all the input/output. Same for sound/music as it uses mikmod for it - don't know how hard it is to transfer this (mikmode) to MOS.
All in all - it is feasible - the question is just: Is it worth the work? As one would have to make a lot of changes.
