Amish,
I like the KISS principal & your fix has that written all over it.
But ....
Your fix only fixes one small part of a multitude of problems with our windows. I'm not 'poo-pooing' your fix, just warning you that you may see other problems in the future. Your fix took care of your immediate problem but be aware that it won't cure the ultimate bane of VX ownership: tilting windows. That is caused by the regulator not gripping the center support arm properly which allows the regulator to tip forward as the window is being raised. Lubricating the front window track weather strip helps this but does not cure the problem. Widening the front track also helps without fixing the problem. Adjusting the regulator forward on the glass helps without fixing the problem.
Your mission, should you choose to accept it, is to fix that problem.
