A Tony and Pepper Wedding?

Now I know this may sound crazy but what if there is a wedding between Tony/Pepper in IW1/IW2, since this may be RDJ last movies as Tony wouldn't it make sense for them to give Tony/Pepper the happy ending wedding, I mean they did start the MCU with them kept building them up as a couple IM, IM2, TA, IM3, and if Marvel wanting to have a wedding in the movie wouldn't Tony/Pepper make the most sense. I can see the trailers started out with Tony/Pepper getting married everyone happy, the trailer being all happy chipper, cotton candy, and rainbows lol but then Thanos arrives on earth causing trouble putting the wedding on hold like any other superhero wedding. In the end of it all they do get married having Iron Man's storyline ending with Tony/Pepper riding into the sunset.
