Not much notice eh ;-)
Firstly, OTV isn't necessary, L2 adjacency is no longer required for network failover (it's UDP unicast).
I'm not sure how you'll achieve your aim where the local servers are concerned, ConfigSync works against you. I assume you want failover to be automatic?
What failover scenarios are you looking at? Priority group activation may be an idea where each pool has the home DC servers set at a higher priority than the remote ones. If the home DC or servers fail, failover occurs and the home DC servers will no longer be available and thus the remote servers will be used.
I don't think that fits the active/active model very well mind.
The ideal would probably be to not run HA, configure each separately and use some other mechanism (GTM, DNS...) to direct traffic between the two.
