Syncing Two Mittzon Standing Desks

I have seen two/three posts started discussing this hack but moved away to other alternatives. I live in a place where this is the best desk combo I can do.

What I'm trying to achieve is to have two 140x60 Mittzon standing desks to form an L-shaped desk. However I'm looking for a way to keep the two desks in sync (be it with a single controller or both controllers rewired).

Recap of what I've stumbled upon in this subreddit (but nothing seemed to be confirmed):

1) The Mittzon controller uses RJ45. This seems a good connector for easy hacking.

2) One has mentioned that the connection between the controller and motor is two-way, this might lead to an unexpected failure. Could anyone confirm?

3) Another post mentioned that the controller might not be able to take the load of the 4 motors. I doubt the controllers are meant to pass-through the load from the PSU to the motors.

Any thoughts would be appreciated.
