    Are Sram HRR hydraulic rim brake levers compatible with disc calipers? If you had a set of the HRR levers you could just attach them to hydraulic disc calipers instead?
    I think the levers were one and the same and it was just the caliper that changed but I cant find conclusive proof online.

    SRAM Spare Parts Catalogue is usually where you have to go, since their other documentation is patchy at best. There's only one master cylinder piston for the whole range of road hydraulic levers, so any lever will work with any brake.
