Are Hijinx icons available anywhere?

I know some say Batwolf icons are compatible but how does that work? Do you need to remove the plastic backing? In this case you end up with a shell of the icon which doesn't seem has enough surface area to stick to the frames. Or do you just somehow cut/file off the tabs on the Batwolf and use the plastic backing to glue to the frames? Ideally icons specific to the Hijinx would be better if they exist.
