Well, this is frankly a pretty clear case of a grossly multi-homed domain that topologically makes sense to be PI.

However, if you wanted to do this with PA, you'd get 84 prefixes, one from each of your upstreams.  You'd advertise 84 locators for your domain via DNS. And nothing in BGP would be in the DFZ.
