Using huge annotations in MapView possible reason for Rejection?

[Kukulcan]

I am using MapKit mostly because I like(d) the annotation stuff. Actually all I want the user to see is a certain area of the map and that offline and online.

So for that "map tile" I use a 640x960 pixel annotation as a backgorund (actually 640x1920 with half of it transparent beacause otherwise half of the standard annotations would disappear under the big one).

It works well and is fast enough.

But I am not sure if "raping" the Mapkit funcionality might be a reason for a rejection of the App. Does anybody know?

I think about instead just using a ScrollView and CoreLocation to put user on it.
