Your theory is correct, but sadly, things aren't that easy.
You can actually enhance many skills in a lucid dream. From physical performance (there's a brazilian study that showed that students can increase accuracy in a "throw a coin into a glass" exercise by practicing in a lucid dream), and if we take dream as an (even higher) degree of mental visualization, then we can take for granted that the fact that you are dreaming about exercising can actually have impact on your muscular mass. This is thought to apply to virtually any physical exercise (even things like playing the piano), and it's also thought that it applies to other mental exercises.
The problem lies exactly on the concept of "becoming" lucid. Despite the several ways of inducing a lucid dream, you need a certain "state" of mind to do it. You could call this something like "constant questioning" or awareness. And you probably already guessed the issue with this: it's not an easy feat to accomplish in a regular basis. We know that certain habits take much longer than the 21 days that once the majority of people thought an habit took to form, and lucid dreaming seems to be on of those extreme cases that might take quite a while to get really sticky into your daily routine. Just ask people like Sageous, who took several years to reach his current state of lucid frequency.
Besides, lucid dreams are not quite common, and don't usually last more than 1 hour, so you'd have pretty limited opportunities to practice. It's a good theory, that would indeed work with a large sample of lucid dreams, but it is not very practical. I really like your chain of thoughts though 
Edit: reading through the posts reminded me of something interesting! There's lots of evidence in cognitive psychology research that you have better chances to recall a specific memory if you are in the same environment of when you previously formed it. That means that being in a lucid and building this "mental note" of lucidity might have indeed some more powerful effects than to simply create a mental note while awake!
