Firstly, in the worst case, extracting the descriptions themselves is trivial, if tedious. The descriptions are obvious, and you could extract them yourself without a script.
Secondly, if this is standard diku, you can download that. If this is not standard diku, good luck. I think that you're biting off more than you think, but perhaps I'm wrong; the stats probably don't transfer directly, so you have to convert that, too.
Third, you *may* eventually run into performance problems with python. Note the may, as this may not necessarily happen, but i've looked into it for all of my make a mud ideas and determined that the memory overhead is a lot and the gil is a problem (yes, yes, pypy).
Fourth, you will almost certainly have to recode all mobprogs from scratch, if the mud these are from used them. This basically means rewriting them by hand.
