The only danger I would caution with a lick centered only approach is that learning a lick doesn’t often teach you how to use it in context or with other coloration, and often leaves a lot out when it comes to chord based soloing and phrasing. You will know it works but necessarily why or ways to morph it. For example the lick you posted above works over a stagnant G7, and you could use it over any bluesy Dominant 7th with extensions as well, but playing that lick over every dominant chord may not teach you what’s really going on and why, or what to do the switch it up.
In other words in really takes a multi-pronged approach and you have to hit it from all sides.
