Ok I have seen the "add Morrigan to your party" tweak before. Can I do something similar without sacrificing any of my party members? Can I switch her for another companion that has not yet been recruited or somehow make her appear on a tavern? If not, this method above is good enough.
The second part of the matter is: once she is in my party, can I tweak the module system so that I can romance her like other party members?
