Who can and can't promote to various pre-existing groups is indeed something we (Fandom Support) can customize. However, we want to avoid too much fiddling as it can get a little confusing when something works on one wiki, but doesn't on another - so it's definitely a good idea to look as alternatives as well, like promotions and adoption.
