I don't think a modern stereo format was ever done for wide-groove 78's. I think but am not positive 
(and I'm sure someone on this list will jump right in and clarify this) that the Bell Labs 45-45 
2-channel format invented in the 30's was for standard wide-groove and 78RPM. I dunno if a modern 
stereo cartridge fitted with a 78 stylus would read that groove just fine, or if there's some 
technical difficulty with that. But, more importantly, would you cut this modern 12" wide-groove 
78RPM record with the RIAA curve? Is that optimum for that format or are there physical reasons 
you'd want to use another curve?

Being realistic, as far as what's a viable niche market, I think 45RPM microgroove LP is about as 
far as vinyl is going to go in modern times. It is becoming the preferred reissue format. I have to 
say, $50 for the typical 2-disk reissue is above my indulgence budget.
