The first step would be to get a "go" from the OSMF to change the website, moving the map further down in favor of other stuff.
Then a temporary group for planning the front page should be formed, with representatives from EWG and CWG. Knowing what goes on the page, we could continue with choosing the tools and making the first draft.
The change will break hundreds of websites and services, so the main thing would be to not go down in legacy support.
@zverik Ok, but I guess it won't be enough for you or me to write an email to convince the OSMF? Should we start a discussion in the forums to get the community behind this?
