Sorry, mate, but I don't subscribe to Sabo vs Akainu theory.
And Gorosei is way too important for Lolda to let Luffy's crew beat. He didn't let Luffy's crew beat the Schibukais and the Yonkos, and will likely not let them beat the Admirals as well. Almost no chance that Zoro or the Cook will even take a sniff at the Gorosei.
I'll give you Koby, but let's not be misleading about Kidd and Law. We already talked about this, but Lolda ensured Zoro and the Cook always play inferior roles to Law and Kidd when they all appear in an arc together. Don't deny this.
Because this pattern makes me believe there is no reason for Lolda to suddenly change this entire dynamic for any reason.
