If the two or more radios are presented as individual network adapters
then yes you could do this.  However, most lower cost multiband hardware
presents a single interface back to the host machine.  You can
multi-home some APs to allow a private WLAN and guest WLAN (there's some
documentation for doing this on OpenWRT for specific hardware) but it's
only a VLAN not a band-split.
