Well im going the shigura route, or shagura as it suits my puerile mind better.
Shimano lever with a magura caliper. The mt5/mt7 calipers are identical.
Info below to help others who may be considering this.
The exact information is scattered across the internet but a huge thread here helped massively.

Use a magura hose. Why? The shimano hose has a bigger dia banjo hole and will be difficult to seal on the magura caliper.
Use a magura barb. Why? The barb is the best fit into the magura hose. The shimano bh90 2.1mm barb will work, but is a little loose. The bh59 2.3mm barb may fit but will be very tight.
Use a shimano olive. Why? Its the best fit into the shimano lever. Shimano olives appear the same, so 1 from either kit above will work.
Use a shimano compression nut. Why? The magura nut is a different size and wont fit.
You will also need the shimano compression nut cover.
Oil is personal choice, magura blood or shimano oil.
Lever is personal choice. Saint is my preferred option.
