Get a phoenix style club to emerge from the curry stained, pastel coloured mess left behind by this current regime. Rather than walk before it can run, crawl.
I don't know if any of you will know this example but I think it is a relevant one. Rushden & Diamonds FC were wound up in 2011 and their winding up meant a new club couldn't apply to the FA to join a senior league till the season after due to their winding up being after the deadline for application. It would be the same in this case for the Broncos as the fixtures for the Championship One have been decided and even though there are only 9 teams competing, it would probably still be too soon.
AFC Rushden & Diamonds were formed and despite knowing that they wouldn't be able to apply for a senior place till 2012, they applied to Youth leagues to get a youth system in place, which doesn't sound like a bad idea. They concentrated on their under-18 side that season and progressed and formed their senior side a year later. By forming an under-18 side or as many youth sides as possible, the new Broncos side will have engaged within their new local community whilst hopefully picking up supporters along the way as well as develop players that will hopefully develop into senior players/fans/volunteers.
In 2012, AFC Rushden & Diamonds formed their senior side, a ladies side and three new youth sides. Five sides would probably be unmanageable for a London RL side but hopefully a couple more youth sides and a senior side would be enough to show signs of progression.
