This is assuming that the EIR is going to be using the same approaches as the IR traffic.
It would be relatively simple to design a cloud break procedure to comply with the EIR rules which then delivers the aircraft to some point which is away from IR traffic and will allow the EIR to then come in VFR without getting in the way.
It would only take one procedure and as it will be above MSa it wouldn't require expensive surveying etc to design.
