best bet is visit a trust and estates lawyer with your wife and discuss options. This is a pretty common desire, and there should be a lot of ways to make what you want happen take place, BUT, if I remember properly, a lot of stuff might have to be done well in advance related to inherited properties tax issues or estate taxes if you qualify. IE, if you were about to kick the bucket, you couldn't whip up some deathbed changes last second and get out of certain tax penalties

I think you can have 50% ownership rights to the properties be held in trust while the other 50% remains in your wifes possession, there are all kinds of ways to tie up the way the property goes.

I also think it might be possible for you to set up a trust like that now, with you as the person running the trust.

A lawyer is what you need to get though, then you can just spell out what you want done, and they can discuss what options you have in your state and federally. Good thing your wife and you seem to be of the same mind on this, best to get it done now with her full consent while you are both in agreement, and both of sound mind and body.
