Noons would get embarassed on the ground against Thomas, and Berto would get outstruck badly by Thomas. As I said Neer is more well rounded then both of them. Are you forgetting Noons got KTFO by Krazy Horse? He looked good against Diaz, but Diaz has the tendency to start fights slow... I think if the fight would've went on, he would've eventually submited Noons... And if they ever rematch, Diaz would embarass him.
Edwards and Diaz would provide interesting fights for Thomas, as both are very well-rounded like Thomas... They both have very good skillsets, although Diaz's has been slacking with his boxing lately, settling for pussy pity pater punches.
