I'm planning on booking two separate itineraries that involves a 4 hour layover in ORD.

The first flight is LAX -> ORD and arriving at 12:05 pm in terminal 3.
My connecting flight is ORD -> AMS departing at 4:10 pm in terminal 5.

I've never been to ORD before so is this doable? I will be checking bags and if it makes any difference, this would be on a monday. TIA
