What u suggested reminds me of the hydraulic power transfer system of large construction gears like digger.
Those heavy machinaries have some kinda hydraulic hub you mentioned, which is basically different in its mechanism for they are electronically controlled. And this hub even has "constant input of power" from engine via mechanical coupler.
The hub is controlled electronically or digitally nowadays. Even with these two spectacular features I can not imagine how to make some kinda hydraulic hub in cycle-size scale.
First of all brake circuits must be separate from derailleur circuit for safety issue. Even front and rear brake have to be split. Then what's new in this case? compared with traditional hydro brake systems.
In the case of derailleurs, there must be 2 hydro split circuits for each derailleur even though they are connected at the hub point.
Otherwise it is more reasonable to use only electronic parts like Shimano's DI2. But then ...there's no difference between Shimano and Rotor.
I think Rotor guys failed at the very beginning(IMO Bike mech does not require tremendous power transferring system unlike heavy machinaries).
There are many reasons that small tools hardly utilise hydraulic power transfer sytem nowadays. Batteries, motors and chipset boards are much better in this case.
Stay home, stay healthy.
