For a floorboard set up, one of Honda's systems in which (I recall) the front lever operated the rear disk and one front disk, would be better. This might not be too difficult a change to make on your bike, if you can source the appropriate master cylinders. Maybe you are considering this?
Well no, I hadn't considered that. But given that for all intents and purposes nearly all stopping comes from the front end and considering what would have to be done to achieve the suggested set up I doubt I would do that.
What I have been thinking about, and I grant freely that I'll have to think about it quite a lot more, is converting the front right disk set up (the handlebar operated one) to the specks of the same year EVs that had a single front disk.
The rational being that they were meant to operate on their own on the front and would have sufficient braking power to do it.
This would mean that the right hand would achieve its expected results without applying the foot brake at all, buy me time, and that the foot brake would help matters along once applied.
It would also be a lot simpler and cheaper than delinking.
The only flaw I can see in this idea to date, is that in total my front brakes could well be much too powerful, with one full steam front brake on the right and another 1/2 steam one on the left being applied at once.
This might not be as bad as it sounds in practice though as I, as I'm sure you have, have long learned to treat the back brake with a great deal of caution, especially under heavy braking.
This is of course because as the weight moves forward to the front wheel the available traction at the rear reduces considerably. It then slides at the drop of a hat. (and yes, I know ABS would fix that, but I don't have it.)
As a result, through another of those long ingrained habits, I tend to stab the back brake peddle somewhat gingerly under heavy emergency braking. I use it more as a steadying brake and rely on the front for real stopping.
As an example, my last bike had a powerful front brake and a pretty useless back one. It was however built in a time when tires were narrower than they tend to be these days (it had 19" wheels). None the less, given a rough chip road surface in good condition it could lift the back wheel nearly a foot off the ground under emergency braking. Not much traction for the rear brake then! In fact it may as well not been fitted!
(I would add that it did this with absolutely no encouragement from me. Intentional "Stoppies" were unknown at the time and would have been considered a very stupid thing to do)
If I do get around to making this brake mod it will carefully tested. It will depend a great deal on the feedback and feel of the brake and I just might have to drop the hydraulic pressure a little in the right front, but that is a relatively easy thing to do.
There are however a great many higher priority items on the bike to spend money I don't have on before that reaches the top of the list.
I also think we may have strayed far from the OPs post and intent.
