Wow. OK. So I guess back to square one, try to get a witnesses attention to review your proposal and then give it a boost if they think it's a good idea.
I am just going to post the idea on a GitHub issue related to SBD and not even drop the link so that the idea can be considered more seriously.

Please drop by and support the idea.
Looks like you left out the bit about pairing it with reverse conversion, and that's what people are noticing. His response was actually my first reaction until I read further through your proposal and found that you wanted to pair it with reverse-conversion. That bit is actually pretty crucial.
I think that it would actually be better to put energy into pushing for reverse conversion, and then it would clear the obstacles to simplifying the reward model through removing SBD from it completely.
Reverse conversion as a proposal has been around for a while and yet it has not been implemented despite its obvious potential to fix the peg. The potential risks have outweighed the potential benefits.
My beef was specifically with SBD as rewards. On GitHub, I think I managed to make a better case for the dissociation of SBD from the rewards system:
