I also have some Rook-strength pieces: Longdebeest (Ö in my notation, CFX) and Dove (Ď in my notation, fFvDbsNbAvHfG). Both are majors; both are also weird (especially Dove).
{Also I think about new piece category, Mezor, which are minor in most variants, but become major in drop variants (such as my Warrior, Copper, Silver, Wildebeest, several Argentinian hoppers, etc.)}
