Sure, such a scenario is possible. Also there is a possibility that Erdogan will give all the caucasian fighters a safe route back home. Think about the scenarios in Russia. Also the Kurds rely heavy on western support. Don't think that they will jeopardize this.
Oh, no tourists will fly to Chechnya.
Also, don't hit my fake drama THAT hard. We all know that Kurds are well organized, there are many of well trained Kurdish combatants, they are highly motivated fighters and they hate Turkey.
From any point of view, Kurds can use additional military equipment with much greater efficiency than ANY militarized organization opposing Russia at the moment.
So, we can safely classified this option as "on the mercy". The amount of possible military and economical damage to the Turkey is immense.
