If you post a picy of your mrs we could give you a better judged answer
I went down the same path (kids needed more room) and i looked around and picked up a pajero TD setup for touring for a good price and kept the TJ to beat on(which i have been doing too much of lately$$$$$) and i wouldnt change anything.
Have a good think about it, i know ive sold too many nice things in the past and kicked my self months latter!!
