There is really no point in an overhead join at an airport with class D zone. The tower should tell you of all relevant traffic, and you should not put yourself in conflict unless you are visual and can take responsibility for avoiding action. There is no signal square, so both the points of an overhead join are removed!
In fact it can be more dangerous, as crossing traffic often goes through at 2000', and can be less predictable than circuit traffic.
