Now and ADJUSTABLE bias valve would be something.... very very common in Stage Rallying where you can alter the front / rear bias on the move depending on road surface conditions, driving style, etc. This was acheived by utilising a twin master cylinder set up (aka a bias pedal box) and altering the amount the piston moved by twisting a knob to move a worm drive rod. In reality as a stage rally driver the only times I altered the bias was when going from tarmac to gravel and the settings just got left well alone. On gravel I liked a lot more tail happy set up but then i tended to left foot brake to get the car sideways into the corner to scrub speed off, wheras on tarmac I prefered almost all the effort to be on the front doing almost all of my braking on the straight to bleed the speed off before the corner and keeping it nice and smooth. Ideally for me a simple lever would have been best to flick between the two settings on a mixed surface stage but these were prohibitively expensive. I still ended up running a third master cylinder with a stonking great vertical lever next to the gear lever for the rear brakes as well for really getting the @rse swinging round on a tight hairpin. Can't see the point on a bike bar for a disabled rider but nice to see some thought going into it, I prefer to control my brakes independantly.
