You can transfer players to servers that use nethernet, as its supported in the minecraft script api, it should be possible: https://learn.microsoft.com/en-us/minecraft/creator/scriptapi/minecraft/server-admin/minecraft-server-admin?view=minecraft-bedrock-experimental#transferplayer
NetherNet is quite new so is not documented much: https://wiki.bedrock.dev/servers/nethernet
I don't have exactly how it works currently, but i am looking into it.
