In reply to Cheese Monkey:
Something I did earlier in the year that may work for you is
Day 1: Plan Glacier Hut (~2800m) 4hr, 1000m ascent, walk
Day 2: Dome de Miage (3600m), 4hr, 1200m ascent, PD (small glacier to cross but dry, and some scrambling at about II), stay at Durier Hut (3100m)
Day 3: Either return the way you came, or, if feeling bold, traverse Aig Bionassay (higher and harder, AD).
