I think your going to run into problems because of TCAS.
Its a pain in the arse because we have to react to it if it gives a resolution. And a lot of company's will require a report as well even if its a traffic trigger.
They still won't be wanting you to get close because they don't want a Go-around on there hands or for that matter airlines safety officers breathing down their necks asking about all the traffic triggers.
Mate's who are ATCO's and also GA instructor's who are the most GA VFR eccentric controllers that you can meet have got fed up of the reports that TCAS generates.
And to be honest most don't actually understand what triggers it and the distances involved depending on the speed of the two aircraft and which way they are pointing. ie if you go head to head with an aircraft on approach it will trigger where as if your tail to nose it won't. I certainly don't understand it. Some one would have to do a study with rates of climb and decent and aircraft speeds to produce a profile round the area that you could work in. It might very well be that you still can't operate into those sites without causing go-arounds if they are banging them in every minute and a half.
