This would either be a simple connector of two brake lever hoses to a hose leading to one disc brake, or it would also have two valves such that if either brake failed or was removed, no fluid would escape, and the remaining lever could continue to operate the brake.
Please provide a sketch of how this might work.
If you had to have all that stuff yeah I'd go Hy/Lex with the GRX interrupters in a second. Would never tell a customer to do this but I'd try it myself. I am not sure of the best way to get rapid-fire shifters on road drop bars though, you might have to go with a "lesser" shifter like a thumbie on a mount that size, or something. There are some lesser band-on paddle type shifters in like 3x7 that would work, they come on department store road bikes sometimes.
