There are many conceivable ways to map 25edo onto the onto the Lumatone keyboard. However, it has 5 mutually-exclusive rings of fifths, so the Standard Lumatone mapping for Pythagorean is not one of them.
Antidiatonic
You can use the b val, which creates the 2L 5s Mavila mapping.

Blackwood
Since 25edo's flat fifth is very flat, even more than 16edo, better options exist for reaching consonant intervals easily, and the the Blackwood mapping is one option.

Gariberttet + Magic
Bryan Deister has demonstrated a mapping of 25edo that functions for both Gariberttet compressed to 1L 3s (7:6 step ratio) and Magic 3L 4s (7:1 step ratio), both having rotated scales, in Waltz in 25edo (short clip) (2024), with both the Blackwood fifth ~50/33 and the Mavila sub-fifth ~25/17 in easy reach. The range is over nine octaves, although with a severe downwards slant.
