Noted, answer to be investigated.
Wow this is a Procedure Design and Airspace one so something beyond charting for sure. The one thing I notice that makes the mix impossible is when the conventional and the PBN procedures are totally different in their tracks, initial, intermediate and so forth. Of course conventional procedures suffer from the limitation of the placement of the navaids but as a rule of thumb you would want to have:
Same entry altitudes and Initial Approach Fixes as possible or close
Same missed approach or very similar
Alignment with the ILS and hava RNAV transitions to it
Improve the airspace design of the holds
All of this will definitely allow ATC to mix the traffic in order to accommodate both navigation specifications, but of course we should be aiming for more PBN approaches and reducing the need for conventional navigation.
