Multiple gateways with same region and different frequency plans

Hi
My idea is to install 1 chirpstack v4 server with 3 different chirpstack-gateway-bridges working on the same region but on different bands and 3 Kerlink or RAK 16 channel gateways with configured basicstation

             - chirpstack-gateway-bridge - 16ch gateway (AU915_0 and AU915_1)

chirpstack - chirpstack-gateway-bridge - 16ch gateway (AU915_2 and AU915_3)
- chirpstack-gateway-bridge - 16ch gateway (AU915_4 and AU915_5)

Is this concept feasible or is another concept needed?

Many thanks for any advice

Stefan
