Dearie, it sounds like you have a plan and just need us to say, give it a try. It is your house and your space. Use it as you wish. Why make your life cumbersome and awkward when you have such a spacious option? (This is a lesson I have learned over time.) Gather help and make the move. Don't like it in a couple of months, then make adjustments. Enjoy! and let us know how this all works out.
