Yes, it can be done.
I have 3 upstream connections and one at a completely alternate site.
Dennis and his team were able to get this working without much fuss.
As far as the redundant core you should be able to do some fairly easy
ibgp between the two gateways to make it possible.

do 1 upstream per router? It's extremely unlikely to have 1 upstream
and one router fail at the same time, I think.
Does that make since?
