This could still be Shanks after this reveal tbh

I'm Always on that Side
That is fair, but it still doesn't connecting with what he said to gorosei about certain pirate due to the fact that Shamrock seems didn't had any interest with "Mortal" World. And coincidentally the next chapter after "Shanks" Meeting with Gorosei, we see Pirate bounty poster being torn up by Imu and Gorosei talking about great cleansing.
Due to Shanks "obsession" to capture or defeat Teach, it's making me believe he is the one that talk to Gorosei, about 50%
 
If Mosa is Shirahoshi, it means that Fish-Men Island are feeling Threatened by whoever Attacked Mary Geoise,
This Confirms that it's whoever gonna wear Imu's Straw Hat & then Attack Fish-Men Island Next, fulfilling Shyarly's Vision,
