The reason I mentioned manage IQ is that it would give you one tool to manage 
everything. You would not have to do much (perhaps the initial setup) in the 
oVirt manager. After that everything goes through manage IQ. Since it is 
designed to manage the managers it is much more fault tolerant which appears 
to be one of your requirements.

As far as max number of data centers goes. I am not entirely sure to be 
honest. But I believe your proposed setup will push the engine beyond it 
limits. I would definitely go with multiple engine instances, maybe in zones 
where the connection to the hosts is better, and then something to control the 
engines from a central location (like manage IQ).
