Double Ceremony - Any Advice?

Sorry long post but My FH and I are trying to plan a double ceremony.
If anyone is familiar with the LDS/Mormon religion, that would be the first and ~required~ ceremony. It’s cost free, under 30 min to get all the religious sealing and legal paperwork done, and only a VERY select group of people may come because it’s within the LDS Temple.

For those that can’t come (a majority of my family) I wanted to give them the opportunity to see me walk down the isle and be married to my FH.
The biggest issues we’ve had to think about is timespan and feeding everyone. He’s never been to a non-LDS wedding and I have but none did anything like this. So I’ll give you our tentative schedule idea and y’all lmk if it’s impractical.
11:15 - 12: were sealed in the temple 12 - 12:45: family pictures at temple (small families)12:45 - 2: couples and wedding party pics (family and friends have this gap of time to themselves. Half of these would be at the next ceremonies location so we would already be there. Short travel time.)2 - 2:30: proceed with second ceremony. (Shorter because we don’t need to be legally bound or have a witness or anything. Just for show for family)
2:30 - 3: pictures with family not at temple & people may begin eating and playing bc the reception place is same as second ceremony location.
Latest anyone should eat would be 3:30. So the gap is 4 hours but there are opportunities for people to grab a light meal or whatever if they need.
Does this all seem reasonable?Thanks for the help!
