You'd be unlucky to be washed out for one week never mind two. A lot of the summer rain out there comes from thunderstorms which blow themselves out quickly. IMO you go to the Alps for lift accessed trails, if you want a quick blast most days and a bit of variety Portes du Soleil is hard to beat.
As hicksville says, if you go away from the lifts there are loads of great options all the way across the Alps. The problem I would have with that would be ETA back with the wife. If you go off exploring, find a new route, or take on a big climb, it can very quickly turn into an epic. Getting back late is the absolute worst thing you can do, you'll pay for it for days.
The other place that has just popped into my head is Slovenia, we were there last year on honeymoon. Beautiful scenery, some lift access, not massive driving distances. Lake Bled, Kransje Gora, Llubljana are all within a couple of hours drive.
