I do not recommend cutting a notch in the fuse for anyone since it is one of the weak spots of the fuse. I flew the AXN with the 2212-06 and found it came up short in both power and flight time. The motor works fairly well in a slow stick.
Have you done any bench testing on that prop? the figures on flybrushless.com show 788g thrust and 60mph pitch speed for an APC 7x5E on that motor, drawing 20.2A. I think the TGS props might a little more efficient around that size.
a TGS 6x4E on a 2212-06 puts out 868g thrust and would have around 80mph pitch speed (the test data assumed a pitch of 4.0", but they are actually 4.6") drawing 23.9A
Did you try a TGS 6x5E or TGS 6x4E with your 2212? remember TGS screwed up the pitch numbers for these props. The 6x5E is really 4.0" and the 6x4E is 4.6".
I would love to see some pics of that 7" prop on a CF
