Yes, you want to use different channels.  Also, you need to have good
spacing between the radios, because even on different channels, closely
located radios will interfere.  We found that putting one in 2.4 ghz
band and one in 5 ghz band worked without resorting to directional
antennas or the like.

You should be able to add either interface in the bridge.
