The current new CP system doesn't really give you much choice. This is partly due to lack of options, partly because all the useful skills are slottable, and partly because there are just good and bad options to choose depending on whether you are magicka or stamina based. You don't get much out of the system now after a certain point.
Even if they added new, interesting options for slottable skills, they might get overshadowed by other skills that are already there, or some might get power-creeped (looking at you, Wrathful Strikes and Untamed aggression which both ALREADY got power-creeped). There needs to be more options for this suggestion to work, but if there were a bunch of new and interesting options, then...
Adding a Bar Swap Mechanic to the CP system would be the right call. Like, this game's unique gimmick is the bar swap mechanic. In this case, I would suggest increasing the amount of slottables per color to 5 to reflect your slottable skill bar, but this might not be particularly necessary. If there are more, interesting options (like some that work based on your weapon or based on your higher stats, hell, they could make some similar to armor skills), and your bar swaps with your weapon bar swap, I could see there being actual builds to be had, rather than what we have now which is just slot the good skill, ignore the rest.
