To figure if some combo will be compatible, consider the characteristics of the products under consideration. In the absence of first-hand experience, I can only try to think it through:
I'd wonder about the #7 being compatible with the AIO- will it bond to it?
AIO provides some protection, so it's gonna leave a presumably impermeable film on the paint (generally speaking, it's the same kind of film that waxes leave). This film will fill in the tiny imperfections in the paint to some extent (this is one reason for the slick surface AIO leaves behind). Will the #7 stick to this film or just slide around on top of it? #7 is designed to get into the tiny microfissures/surface imperfections/pores of paint- will those be present (functionally speaking) if the paint is coated with AIO or will the AIO fill them in and leave something over top of them? I don't know, but I have my doubts. I guess it comes down to how the non-oil ingredients in the #7 behave.
IMO it'll be like putting a glaze on top of wax- it provides a temporary boost in appearance, but it won't last long because the glaze (usually) doesn't really bond to the wax very well.
I'd guess that it might work out OK looks-wise but won't last too long. I wouldn't try it on black though, I'd worry about streaking from the #7 on the AIO.
But hey, that's all conjecture

If you try it, report back on how it works out. We'll see how well my theory works out in practice (I'm fully prepared to rework the theory

and if I'm wrong I'll know better for the next time this comes up).
