The color palette and the texture would have to closely resemble that of the original potato-starch autochromes. I'm sure it would be frighteningly expensive so I'd have to be able to put together a kickstarter type project to get funded to do it. But if it was there, I'd definitely try it - I've got a few whole plate sized glass plate holders kicking around I think that I could use to shoot it, and I definitely have 11x14 glass plate holders which would be tres cool - could you imagine an 11x14 color glass plate original?
