If the snow was decent you could probably ski tour a lot of it - but as I discovered on the weekend, even relatively gentle slopes with ice on are tricky, and the skins don't really seem to grip... and result in you sliding back down the mountain! Ski crampons would be a great idea...

All the peaks are skiiable downhill in the right conditions, but you might have trouble skinning up girdlestone for instance (more usually done with two tools and a rope).
