As someone who moved the other way, from an '09 R1200GS through several others to a Wee...I'd say you'll miss it and you'll be back.
The ergos on the BMWs are excellent. The engineering is amazing. But those are HEAVY monsters - I had a leg issue develop on a long road trip that took me through Joplin, Missouri. Five days after the tornado, which, being on the road, I knew nothing about.
My leg was painful and swollen and there were NO medical facilities available for any but the most emergent needs. I had to make it to Texas to get to medical care, and I did...but the thought of losing it on that big, heavy monster; or even just saddling up or stopping at lights...was scary.
The Wee, being over 300 pounds lighter, is much more to my current abilities. Yes, I miss the 130-mph Yee-HAAA! runs. Once in a while I do. Most of the time those are impossible anyway.
I guess it depends on how often the wife likes to ride along. If she's with you all the time, it's a good choice. If not...you may want a smaller machine for solo trips.
Have you thought about teaching her to ride her own?
