I feel like 'radically' reworking anything is a great first step in increasing errors while the new processes get ingrained. There needs to a measured and meticulous approach to reworking ATC if it is to happen.
I’d consider significantly raising controller wages and improving working conditions to be a fairly radical proposal in at least the US’s current political climate.
The average controller makes 120K as it is. That may not be a lot for people in the software world accustomed to making big bucks, but it's not terrible -- close to 90th percentile.
