“In my opinion any ILS should carry a hub of NO GO airspace without radio permission. Infringe it and get the book thrown at you. But its the regulators at fault not the pilots whether they be microlights or otherwise.”
This is a great solution for you but can have very unpleasant side effects. There are an increasing number of corridors between CAS which contain considerable VFR traffic. If you narrow the corridor by another ten miles as suggested then you will be forcing large amounts of non radio traffic to transit in a very confined space. Non of this is a problem for an ILS in IMC, as the VFR traffic will be VFR, but on a good day doing a practice ILS in class G, you have to operate see and avoid.
