Can you imagine the outcry if this happened on a VGS? The Coroner and media would have a lot to say. Please, I am not trying to point-score between VGS and BGA, but this indicates why your proposed use of BGA clubs would not work without radical change.
I am aware of the BGA accident statistics but the statistics you quote will be for privately owned gliders and not for Gliding Club 2 seaters !
