I'm not very interested in redesigning English spelling. However, it seems feasible to automate most of the encoding. I'd think most words could be rewritten with a lookup table, except for a short list of heteronyms. For printed material, I'm not convinced teaching kids how to read "Obsolete English" would be harder than teaching them to read cursive.

Updating grammar would be a giant pain in the neck. Saying "we're gonna write 'cat' as 'kat' now sounds a lot simpler.
