I've been doing something similar with the books I use. I have a handful of LH patterns I want to be able to improvise over, and a bunch of RH licks to sprinkle in my improvisations, so I've spent tons of time practicing the various LH and the various RH. It took a lot of time, and I still have to do some maintenance practicing if I haven't used a LH in a while, but it's paying off. It's slow, front-loaded work, but now things are coming together that much faster.
Enthusiastic but mediocre amateur.
