I did. Purchased the necessary lines and valves from a RHD part out in the UK.

The tricky part wrt RHD is removing the master cylinder with the engine still in the car. Takes a wide assortment of sockets and wrenches, but it can be done.

I'm pulling the motor this winter so that shouldn't be an issue, were you able to keep any of the lines other than the ones running to the rear?

I think the engine bay lines all became redundant with the new proportioning valve and 3-way valve under the master cylinder.

Now just two lines run along the fire wall to the proportioning valve - one from the 3 way valve and one from the master.

The 3way valve also supplies a line to the front right wheel and a second to the master.

I think the front left wheel also has a new brake line to the proportioning valve.

Does anyone have a picture of the JDM three way valve? Why on earth Toyota used a different system for RHD and LHD I'll never understand. And does anyone know why the 88-91 and 92-93 proportioning valve are different?

I don't believe they are, toyota just charged part numbers at that time for some reason. It took the guy at my local dealership 15 minutes to find me the correct timing belt for a gen2 engine cause two of the part numbers were discontinued...

Awesome, thanks Corey! I was completely misinterpreting that parts diagram apparently.
