In reply to minus273degrees:
Lots of clubs are formed by groups of individuals, think of the Rock and Ice, Alpha, Black and Tans, Creagh Ddu etc and they were not affiliated to anyone for years, if at all.
Do the same, and if you want more organisation join the local club and work as a small group inside it. Being a member means you are part of the BMC and can use some huts barred to you as individuals.
