In reply to miniwheat:
Lots of opportunities, these are ones I've done:-
Main Dolomites:-
Up VF Brigadate Tridentina, stay in Sella hut, down VF Vallon, up VF Piz daLech, then down (check Vallon isn't broken).
Up Vf Rene Da Pol, Stay in Laurenzi hut, down VF Ivano Dibona (hut might be shut due to cablecar replacement?)
Up VF Masare & Rotwand, stay in Vajolet hut?, Vf Santnerpass? Vf Kesselkogel?
Brenta -
Groste cablecar up, VF / path to Tuckett hut for lunch, VF SOLSAT, stay at Rif Alimonta, down VF Spellini, along Orsi path, VF Bernini back to Groste. Or Bochette Alte instead of Spellini and Orsi if you can read maps properly .
In short, get a guidebook and work out the enchainement possibilities. Biggest potential problem will be getting back to your start point.
