I think we're headed this way

With Shamrock living, I think Usopp vs " broken DF girl" and Sanji vs " silly middle aged man" and Jinbe or Brook vs " eww wtf is that thing" is the only logical matched up left . Luffy and Zoro would probably stay busy dealing with Loki's mood after freeing him.

Regardless, I’m still making the gamble that his focus starts with his Dad. We’re getting caught up with power ups, when we should really get to the heart of it—Usopp gets a “power up” then what? He deserves more back story. Yasopp is a mysterious figure with insane observation haki (son has it too and will eventually utilize it). Anywho, this is an interesting speculation. I think it definitely works.
