Easymesh on PiFi

I am running a PiFI in France with Tailscale to give me a Wi-Fi LAN which appears to be located at the Tailscale exit node in the UK. I am using the wired Ethernet port on the Pi as the WAN and the WiFi radio built into the Pi to provide the LAN. It works quite well but the range of the Wi-Fi built into the Pi is rather limited. I also have an unused Wi-Fi 6 router that can support Easymesh. Is it possible to support Easymesh on the PiFI (perhaps with a usb Wi-Fi dongle) ?
