I'll have to take your word for it – I'm curious if you have tried it though. I can certainly imagine that it might be feasible (even at lower resolutions) with enough stirring of the 'linear algebra pile'.

Not meaning to rain on your parade though – congratulations on a great idea!

No rain! It's a great callout. We'll see what we can do if for no other reason than to understand risk.
