Answer 1

Is it possible to back AWS ELB with EC2 instances from different regions?

To my understanding ELB can't do that.

Note that there is a good reason - introduced latency across regions as opposed to AZ latency. However, you could mimic something like that using Route53 or any other DNS that supports GSLB (Global Server Load Balancing) or similar approach.
