Honestly I don't think this could be achieved on Android the same way Apple does for the same reason we can't all get timely updates the way Apple does. Too many cooks in the same kitchen. Even if Google implemented something like this, different manufacturers would end up tweaking it, so it wouldn't be the same thing. The only way this would work is if Google implemented some sort of rule that the manufacturers couldn't change it in any way.
They would just make it part of the GAPPS package that is required to be installed. Carriers wouldn't be able to modify the actual app since it's a Google App.
The trick would be getting people to use it over the normal SMS app that also comes with phones.
