you said:

you do not have to run Bump maps through the AI that is not a good Idea normally you just do it on the Diffuse map, maps that affect the high detail of your render. Getting a good diffuse map with loads of thin details will also solve allot of problems with the bump map that might not even be necessary any longer, the skin does not need to be bumpy and look like it been hit by micro meteorites, Mostly an issue on releases that the artist is trying to add details with bump because he's diffuse map is just flat with only minor skin details.

Baked in highlights and shadows will not respond correctly to lighting. For that you either need sculpted in detail (which more than likely will need subdivision), or really good bump/displacement/normal maps. Depending on diffuse alone will not be adequate for a physically-based render engine.
