I don't think so really. The [AJ]SF should be fairly straight forward - you can get hold of night recce and flash pods from Maestro Models (scroll down a bit, MMK7208 and MMK7209), then it's just the markings that may pose a problem. The AJ could be harder, you will need to construct the pylons and, probably more tricky, the gunpack. Broplan did make a gunpack, but I've never seen it actually for sale anywhere. You'll also need to decide whether you are going to extend the fuselage by 2mm or not - irrespective of which boxing you have.
