I believe there are lots and lots of story elements in the homestead level. You'll need to make a list for everything going on in there so you wont break the main campaign, then you'll copy/paste everything to cyseal or anywhere else. This will take a very long time to do as the homestead is the most important thing to the whole campaign (dunno how much story editing is required, probably lots)
For companions/hench just select and delete
