Of course there isn't actually any need for BRCA sanctioning. The BRCA is a convenient, well established governing body but there is no reason it actually has to be the only one.
It is entirely possible to set up an alternative body just dedicated to 1/10th Off Road. I already know of clubs who have arranged separate (ie not through the BRCA) insurance and do not require racers to be BRCA members so if a new body formed it could like offer insurance. The Oople and RRCi series have shown you don't have to be the BRCA to run a national series.
The only downside is that IFMAR won't recognise the 'alternative' as the 'true' national series for Worlds qualifying.
And we can have no silly homologation rules and online AGM voting too
I actually reckon this idea is more viable than trying to change the way the BRCA 1/10th section works. The comment about busing in 100 people to the AGM in order to swing the vote is the truth - and the reason many are put off attending. Its a long journey to the AGM venue and unless you are already a well established name in national circles its highly unlikely anyone will listen to you (I may have never attended a BRCA AGM but believe me I've seen enough of these in other fields to know how it works) so its a wasted journey unless you bring a LOT of mates to back you up.
