What other genera are confirmed to be able to hybridize with Astrophytum?

I can't seem to find a comprehensive list specifically for Astrophytum anywhere online. Astrophytum is my favorite genus of cactus and I am really interested in creating intergeneric hybrids with it.

I'm unsure about other genera, but Astrobergia is a well-known cross between Astrophytum and Leuchtenbergia. I'm not an expert on cacti lineages but that might provide other options on what hybrids may work.

As Leuchtenbergia are 'weird Ferocactus' in some form, perhaps an Astro x Fero can be made? If you count chimeras it appears there's already some Astrophytum caput-medusae x Ferocactus glaucescens on the European market, though I only just looked this up so no guarantees on legitimacy. (…but if you count chimeras then any graft-compatible plant can theoretically make a 'hybrid')

I don't think there are any confirmed intergeneric hybrids with Astrophytum. Astrobergia has long been suspected to be nothing more than a "kikko" cultivar (elongated tubercles) of Astrophytum ornatum and in my limited experience I agree. I'm not sure how up to date this is, but I believe Astrophytum and Echinocactus are sister clades? I wonder if anyone has experimented crossing these two.

I do think Echinocatus hybrids are possible with Astrophytum. I've heard reports that Astrophytum ornatum is an ancient hybrid between Astrophytum myriostigma and an echinocatus that became self-perpetuating in the wild. I'm pretty sure Aztekium is a pretty close genetic relative of Astrophytum but I haven't heard of any successful crosses. I've also heard of an Astrophytum asterias X Lophophora williamsii cross but have never seen photos to back this claim up.
