That's a good way to understand unfamiliar theory at first but it's going to limit you in the long run. When you were learning your major scales, you probably learned that F major is a lot like C major, except you start on F and the B is flat. That worked for a while until you got used to F major. Now you don't think of it as "C major starting on F with a Bb"....you think of F major.

Eventually you're going to want to learn F dorian, rather than "Eb starting on F". It'll open you up to new ideas and understanding in the theory and improv. It's tedious at first, but no different than learning different major scales.

Also, as previously posted, you're soon going to run into scales and chords that don't relate to major keys as easily. The first time you see F7#11, you're going to have a tough time deciding if that's Bb major with a B natural(??) or C minor with a B natural(aka C jazz minor). You'll probably be much more comfortable in the long-run learning that lydian dominant is, how it works, and what sounds great over it.
