DO NOT under ANY circumstance put your W on your health insurance. Just don't do it.
Your marriage is classed as a "young marriage" (under 10 yrs in this state after ten yrs. it is vintage and things get VERY sticky) and since you both work/provide your own insurance there is a good chance neither of you would have to be support. But I would be VERY cautious about all your W's medical problems. If she does get a firm diagnosis she might be classed as an unhealthy person via the state (I am due to my Lupus) and that will change the game drastically.
