Tea Party.. What Big Mom's plan on her big event..?

Big Mom plan for her Tea Party not because Vinsmoke Jajji agree on engagement between Sanji & Pudding..
But..
She plan it for a long time..
Wedding is just one of the program..
Or Wedding Day is exactly the Tea Party..?

What do you guys think of this..?
For me..
Big Mom already prepare many program in her Tea Party's event..
And the program are:
i) Welcoming Guest's ceremony
ii) Exchange gifts between Big Mom & Vinsmoke Jajji
iii) Wedding of Pudding & Sanji
iv) Tea Party

Briefly about the program:
i) For Welcoming the Guest.. I thinks that Oda want us to know and see who's coming for it.. But there will be unexpected Guest that will coming after that..
ii) For Exchange Gifts.. I think Big Mom & Vinsmoke will exchange gifts first before the wedding.. Maybe Oda plan for Tamatebako Box (National Treasure) been brought there maybe as the way Big Mom show off her treasure..
iii) For Wedding between Sanji & Pudding.. Pudding already discuss it in front of Reiju and Sanji listen to it at that time.. (Maybe Pudding knew Sanji was there and want Sanji to leave before the wedding but Sanji want to stay to help his family.. The twist plot will be reveal in this program)
iv) The fight start right after Pudding shoot Sanji.. Then everybody will start to follow Capone's plan.. Not 100% follow.. Maybe there will be a change a little bit according to unplanned matters such as unexpected guest or SH not yet trusting Capone's whole plan..

Note: Tea Party was planned by Big Mom just to celebrate the victory with her children.. The victory over Vinsmoke & Germa 66.. Maybe at this tea party.. Big Mom plan to ask all her children to become giant as she forced Ceaser to run the experiment.. Maybe at Tea Party she will asked all her children to become giant so that they will be equal or same having tea party together at the same eye level..

What do you guys think..?
