I'm not at home right now and I can't try your method, but after reading it I can guess that it won't work, the RPH and LSPDFR worked for 5-6 hours with these plugins and scripts without crashes and bugs. The problems, as I said, began after the replacement of models of all cars.
But, if your method works and nothing crashes, what can I do to get me to play with these plugins, because I really like them?
