Speedfusion tunnel from WiFi WAN to WiFi WAN

Hello,

I know its not supported but Im worried any feature request or you have roadmap for the following design.
Two Peplink MAX units will establish a speedfusion tunnel over WiFi. There is no 3rd party WiFi service or AP to which the WiFi-WAN supported Client side can connect.
So, Peplink in Client mode should directly connect to Peplink in AP mode. It means, Peplink Wi-Fi WAN feature should support WiF-WAN Client (its default) and WiFi-WAN AP.

I thought a little bit about which method we can use. A WiFi SSID will be assigned a VLAN, same vlan will be used for a virtual WAN interface ( such as loopback interface), So SSID and virtual WAN will be bridged. So, Virtual WAN can terminate the tunnel request that is coming from WiFi-WAN of remote Peplink.
I want to use two Peplink units, and one Overlay tunnel includes WiFi, Cellular, WAN underlays without using another modem,router, AP etc.

Thanks for your comments

If connecting directly, you will need to disable NAT (use IP Forwarding mode). If there are routing devices in the middle, you will also need to forward speedfusion ports to your “master” side device.

This was working for us once upon a time using the device connector series , but no product has replaced it, it allowed for speedfusion connection on the lan side ip.
