In reply to Aigen:
have you checked out the DAV/OAV hut list online? It's usually quite useful in this regard.

Re linking tours together, have you considered stuff in the Stubai which can link easily to Oetztal (both these described in O'Connor vol 2 (Cicerone)). Many of the huts in these areas are open during the touring season, though not always the ones O'Connor describes.
We linked Stubai with Silvretta once, skied out from Stubai to the West into Oetztal then bus/train/bus to Ischgl. With an early start and using the lifts above Ischgl, it was possible to go straight from one hut to another without wasting a night in the valley.
have fun
