in adapting some magura hydraulic cantilever rim brakes for use with drop bars, i have drilled a cable end in them,use linked cables with a binding bolt,
and use ergopower levers on the drops-to pull the magura levers on the tops- to actuate the brakes.
I did this because these brakes work superbly, but the drop versions are now very rare, thaey stopped making them 2001 but if a set can be found apparently the lever can be put onto several magura brake types.
Dont know whether this helps at all but there are often ways of adapting gear.
