I noticed on onyx's website that the xd freehub body has been discontinued. I am assuming I can order the xdr freehub body and run a spacer to use gx and higher for my next cassette swap. I will confirm with onyx that this is doable, but I would think it is an easy swap. I currently have an 11 speed driver with a 12 speed eagle nx cassette, but I would like to run a higher quality cassette on my next swap and to save some weight. Has anyone on here done this?

I reached out to Onyx about going from HG to XDR and they confirmed that it was easy:

"Sorry the freehub is buried in our parts section.
Link below if the freehub to fit the Vespers. When changing from HG, the same drive side endcap is shared.

Not certain about whether or not they still offer the XD but I think XDR with spacer would work like you say. Possible that you'd need to replace an end cap depending on configuration, but I'd just email them to confirm everything. They've been really helpful/responsive when I've reached out.
