In reply to Andy Nelson:
One option would be to go up to the Glacier Blanc hut, taking in something like Graine de Cezanne on the way (30mins walk above the hut, not diffuclt at all). The following day you could do the South Ridge of the Pic du Glacier Blanc (AD), a good ridge climb. The following day you could do the traverse of the Pointe des Cineastes (AD). This would provide you with a good couple of days where the climbing is never desperate, the altitude never too high, and the views always good.
Later on, you could perhaps consider this as a significantly more difficult route. Walk up to the Pelvoux hut. Do the traverse of the Aiguilles du Sialouze (D). A splendid climb on top quality rock, although the descent can be complex. The following day you could do a traverse of Pelvoux, descending to Ailefroide. This is a wonderful moutnain day, and although not involving any ridge climbing if done by the 'normal' route, it is not in the least a dull glacier trudge. One of the best low grade Ecrin mountain routes.
If you were hoping to be round the far side (La Berard base), you could consider going up to the Lavey hut (a lovely hut ~1 hr 15 from the road). From here you could do the Arete des Papillons on the Aiguille d'entre Pierroux. The next day you could do the Tete des Fetoules, although this is perhaps a bit more of a slog than you are looking for.
From the Soreiller hut (dibona), the obvious route is the north ridge. Really though, this is a very short day. The bulk of the face routes on the dibona are ~TD, but the Berthet/Boell/Stofer may be worth looking at. Of more interest to someone looking for AD ridge traverses would be a traverse of the Soreiller Occidentale - Soreiller Centrale - Aiguille Dibona.
Hope this has given some inspiration. It is quite hard to gauge what you are capable of as I am unaware of the extent and type of climbing you do in the UK. For this reason I have included harder options (Sialouze), and easier alternatives (Arete des Papillons, Dibona standard route), as well as some in the middle (Pic du Glacier Blanc, Cineastes).
