I'm playing this interesting variant. Some remarks:
1) The presentation line says "9x9 variant with extra Queen and Bishops conversion rule". >> it should be corrected to 9x8 as it is not a 9x9 as originally designed.
2) As 9x8 its originality is weak too. In Pritchard's one can find two preceding CV, also briefly addressed in this website. Ultrachess attributed to D.Trouillon, early 1970s with the same setup, where it is possible to transpose B and N once. Also Active Chess (G.Kuzmichov, 1989) for which, apparently, some research had been done to find the best setup. Here the extra Queen is put on i- or j- file. Gollon also explored this game, preferring RBNQKQBNR baseline.
Another option to change the square color of one Bishop would have been the solution adopted in Not-Particularly-New Chess by Peter Aronson (2001): having that piece first moving as N (non capturing) and as B on subsequent moves.
