No... Switching from blues to reds probably won't automatically make you better, and may not even help in the long run, even if reds have a very slightly lower actuation force. There is always a chance that you improve slightly, but if you do decide to go buy a keypad with red switches, keep in mind that nothing could change.
You will still need to practice, train, and go through all the normal motions of improving regardless of the switch type you have, and that is the key to improvement, not a 10g difference in actuation force.
