Spend some time on golang-nuts, proposing ideas from "languages for academics".
>writing a compile-to-go language.
Why not fix Go instead?
You can't fix Go directly. You have to convince the language designers that it needs fixing. The fastest way of doing that would likely be at least a proof of concept, or better yet, a complete tool that gets significant community uptake.
I don't think it's such a bad idea, considering how stable the language itself is, it's a pretty solid bet.
