Right.... after sorting myself out regarding uploading images I find everyones posted everything I wanted to! 
However - fair play Sam, awsome effort if you pull it off. Camping on the true summit is really only possible if you have a heavy drop of snow which ices over as it is just jumbles of rocks and no flat bits. The east side has small ledges, like the photo's suggest.
Not really much proper snow this time of year, just wet, greasy and possibly icy. Snow generally comes in March, but nothings predictable nowadays.
Can I suggest the "football pitch" on the Y Gribin ridge nearby. Nice views, airy pitch but pretty flat and grassy!
