I am not too sure about zoro getting above 1.5 but he has reasons to get above 1.5
defeated king which justifies at least 1.4 and he is the strongest subordinate of luffy
my speculations are
zoro 1.4 - 1.6
sanji 1.33- 1.5

However, Wano arc has so much more to come and Zoro and Sanji each have more plot lines to show. As such I’d say they’ll show to be massive issues with the world government. I predict Zoro will be seen as a leader of an unknown powerful army being the samurai of wano while Sanji will be the protector of the only person capable of decoding poneglyphs in robin.
Each of those would cause decent bounty boosts as such about 1.82 and 1.77
