guess all you have is improve the housing with Nokon bead sleeve type, flexible but compression-less,
and try the Salmon KS insert pads ..
and anticipate your stops earlier, so that you don't have the last minute panic stops.

maybe where the lever is, on the bars ,moved up, can give more swing arc
before bottoming out..

Potential kludge.. inline travel agents.. normally supplied as a road lever
to MTB disc brake cable pull increase
[but you need a bolt to the frame/fork to mount those]
