For the OP, who is a pro and can justify spending money on 2 systems for 2 purposes, I would say this is not crazy, especially if the lenses for the two different uses don't overlap too much. Or, if the cost of the overlapping lenses is not an issue to the OP, then, well, it isn't an issue.
I'd also echo what at least one other poster said about the possibility of medium format digital as a solution. If you are going to stay with Canon for one side of your business, you have the freedom to choose something even more use specific than Nikon, if it's something that you like to use. If I had the business, and the means, I'd rent a digital MF rig and a D800E and see which I liked better as far as usability and results.
For me though, an amateur shooter that can't afford to dabble in two systems worth of glass, splitting systems does seem crazy. I would have to choose one or the other. Not that I wouldn't want to have both. I just couldn't justify it.
