I wish someone like Columbus/Reynolds/Tange could catch on this. It'd be awesome a road bike made of fancy/extra durable stainless steel tubing, lugged, horizontal top tube and that classic geometry but with disc brakes and thru axles.

Why though? Cr-Mo steel tubing is already superior to 304 stainless in every relevant measure, except surface corrosion. In particular this article discusses fatigue behavior, and Cr-Mo has a (much) higher fatigue limit than 304.

If you exclude cost as a relevant measure.

Stainless is more expensive as well
