The SBX is different enough from the SBT that I'd suggest you make an SBX badge, especially since Light has made it clear that he intends to host it with a similar periodicity as ladle.
Edit: Reading your previous post, it seems you had the idea to make an off-series branch of badges. The tournaments I singled out, could be labeled as such, no?

Edit again:One more post and I hit 300 posts!!!
