Dio made but one imagining, as far as I'm aware, unless he managed to get hold of a clear picture of it from the game it appeared in (which I have never come across in my many searches). It was an absolutely fantastic custom, though, and I understand not wanting to attempt to do the same thing, haha.
HMS generally use emblems instead, only a few HMS, those based on the 5 Holy Beasts, came with stickers depicting bit beasts. I would suggest slightly modifying Wolborg MS' Emblem perhaps (as phantom fox's looks rather odd to me), or making one from scratch - which isn't actually all that hard, given simplicity is a huge part of those emblem designs.
