Oh, thats interesting, so the normal electoral process, but a randomised but then self selecting group of candidates.
I guess the independence of each new member coming in is the perceived strength here.
But i'm not sure 'independence of each member' would be a strength in this format. Because the erstwhile independent members, since they're, at first, randomly chosen community members, would likely begin forming impromptu and easily led blocks/factions within the parliament once there.
Essentially ending up with a weak Party system that is as easily corruptible as the current situation, but less effective as a voting and policy force as the current situation.
Or have you got a different strength/benefit to this system in mind?
