13 speed HG body alternative to SRAM Xplr?

[glitch]

I would love to build up my new gravel frame using something like a 13 speed Rival XPLR derailleur.
But all my wheelsets are HG body and I would like to keep it that way for interchangeability between bikes.

Is there any alternative 13 speed cassette with hg fitting out there which has been proven to be reliable?

Otherwise might just go mullet using none transmission eagle and 12 speed cassette of choice as in the past, but it would be fun to try the full mount solution

AFAIK nobody makes this because the whole point of SRAMs wide range gearing was to start at a 10, and the smallest you can fit on an HG freehub is an 11.

there are some 13 speed hg cassettes on ali https://pl.aliexpress.com/item/1005009369286201.html however I don't think it's going to work with sram xplr. 13 speed sram is t-type mounted directly to the frame and their 13 speed cassette is slightly wider and i suspect have a different spacing. Those HG cassettes should work with a wheeltop groupset though.
I also don't fully understand the argument about wheelset interchangeability. You can just swap the freehub body in 5 seconds without removing the cassette. I have 4 chinese wheelsets 2 HG, 1 XDR and 1 microspline and each with their own dt ripoff freehub and they are all compatible with each other. I constantly shuffle the wheels around but each bike has its own freehub with cassette.

Well I have 4 different wheel sets for road and gravel, plus three mtb wheelsets. They sre all of different brands, sonit would require a lot of different new freehubs, if even possible to find the right one dor some of the older wheels.
