Sounds like an expensive exercise with little safety benefit to me. Creating swathes of Class E that are going to require ATCOs to provide a service at a time when there is a national shortage is surely not the best solution:ugh
Given that aircraft flying VFR in class E have no obligation to receive an ATC service, other than separating against other IFR aircraft which will likely be receiving a service anyway, why would vectoring in class E be any safer than class G?
