Hub for the inputs is fine but I think I'd need 3 physical ports in that case - 1 for the hub and 2 for the separate outs.

However... it just occurred to me I could connect 2 together for cross signaling over the other pins and have 2 in and 2 out that way.

Another idea, STM32Fxxx...3 physical USARTS in at least some of them.
