Obscure less popular Quads, will we ever see them released in a digital format?

[Which_One_Is_Pink]

I have recently started going through some of the many Quad conversions that were around 2008, 2010 when I was laid of . I haven't listened to most of these for years and as I have been listening to some of them I was reminded of some of the more obscure bands that I really liked and had kinda forgot about. One example is 'Babe Ruth' which I owned on stereo vinyl since release. While is not a top tier band, for me, it is right up there with the more popular bands I like and in Quad it gets a little bump up as it has a pretty good Quad mix. I'm sure this is unlikely to see an official release but I never expected that Be Bop Deluxe or Bill Nelson or IQ would get a multichannel release and yet they did. So as the saying goes 'Hope springs eternal'.
So my question is, what other obscure bands had Quad mixes that members here feel are just as good if not as popular as the more popular bands in Quad.

Not really obscure but due to the general unpopularity of surround sound in Japan, I doubt many Japanese quads will ever make it to digital. Right now it's just been some QS-encoded CDs and maybe the once-every-5-years issue on SACD by Sony.
