Why do you want to do that? Plastered houses are the nicest that exist and require less maintenance than wooden facades with painting, washing, etc...
If you're still going to panel the house, I would think the most complicated part would be fixing the windows and doors. You'll need to add new flashing and trim. If the windows end up too far into the wall, you might also want to move them out, and that's quite a lot of work both externally and internally in that case.
