Lumatone mapping for 72edo
There are many conceivable ways to map 72edo onto the onto the Lumatone keyboard. However, it has 6 mutually-exclusive rings of fifths, so the Standard Lumatone mapping for Pythagorean is not one of them.
Diatonic
You can use either the second- best alternate fifth:

but these do not cover the full gamut or make the best-tuned intervals easily accessible.
Miracle
Instead, the most efficient way to put the best-tuned intervals near each other while allowing access to all of them is the Miracle mapping, although this does reduce the range to a little over three octaves.

Semimiracle
Slicing the period in half to produce semimiracle makes ratios of 13 and 17 just as easy to play as the 11-limit ones and also keeps octaves closer to horizontal.
