You are late with that: it's actually happening.We could achieve a fully phonetic alphabet by encouraging everyone to pronounce all words as they are currently spelled. Most people are resigned to the notion that english spelling reform has zero chance of success. But pronunciation reform could be many times more likely to succeed.
As I've told it somewhere, I'm working in a kind of international environment, where English is the common language - but there are no native English speaker there.
The result is, that everybody is trying to speak the written English
I've made a quick survey back then, and many similar places does the same. Also, we could understand each other rather well, so I guess it's really so.
Also, it was a common topic that it's so hard to understand anybody from USA or GB.
So I guess native English speakers are up for some hard time soon
