Hello Dean, great article and a really solid idea. I like the way that us BPs could graduate through the ranks too, it would surely reveal some up and coming stars quickly.
The 5% thing has never been an actual proposition though as far as I'm aware anyway, this was always the maximum inflation cap and so many have taken this to mean it is the potential income. It has always been that it was going to be split three ways, BP rewards, Standby BP rewards and Worker Proposal Fund which gets the majority of the inflation.
As you are probably aware the new release of Dawn 4 due on 11th May now seems to include new notes on the pay model from Block.One which can be seen in this post from Dan Larimer on Medium https://medium.com/@bytemaster/introducing-eosio-dawn-4-0-f738c552879
I wish you the very best of luck with your BP Campaign and I look forward to following your success on launch day if we do not get opportunity to correspond again before then.
Best regards
Roger Davies
