I have not suggested a tower. What's wrong with terminal E run from the en route centre as per USA and Canada. Also brings in mandatory transponder for VFR so makes even safer.
And why not put in a Unicom like the USA. Can give known traffic and WX.
The public won't be able to believe that Airline pilots are forced to transmit on a non ATC frequency and arrange their own separation with 1930s radio procedures when in cloud.
