ZHA Vs Zigbee2Mqtt

Hello
I am made my home assistant installation and like many person I may be trying the two solutions…

Is it possible to have a gateway (coordinator…) under ZHA and other gateway (second coordinator) under Zigbee2Mqtt ?

I have a gateway Sivercrest lidl hacked (non tuya cloud) under IP connection…connected to ZHA with zigbee material A B and C…
I am very happy of this…

I have dongle Usb Sonoff P. I want to add to Zigbee2Mqtt only…
So I use this with zigbee material D E and E…

Thanks
