Don't sell yourself short mate. Its good to see that sort of situational awareness regardless of your licence. I'm sure if I was flying into an aerodrome I would like to have at least a mental picture of what else is in the circuit.
I see the problem being, that you have to identify yourself on the radio. You are not a CA/GRS or UNICOM but hey, why not walk over and stand next to the aircraft you usually fly and use that callsign?
