I'm a bit in the same boat as you. I love big cohesive aesthetics, but I also have so many artists and styles that I admire. So my compromise is that I'm reserving my upper body for large scale cohesive stuff with my truly favorite artists, but I'm using my calves and thighs as my "collector's area," with smaller pieces of meaning, styles that I only want to dip my toe in, or specific artists' work. That way, I get some huge chunks of synergy up top, but still get to collect bits and pieces.
Any approach has ups and downs. Whatever your plan is, at some point you just have to pick a direction and pull the trigger.
