Carol, I think 90" is too close a connection even using Mobile Passport. The walk from the plane to C&I is long, even with the moving sidewalks. The hold up is usually at the re-checking luggage & going thru security bottleneck. I'm so use to flying thru ATL I don't see the size as an issue. Once you're thru security you're on the train going to your concourse, maybe 5-7". A minimum of 2 hours is what I aim for.
