Worried wedding invites will spark jealousy

Me and my husband are legally married but want a wedding. Our wedding is set for the May. He wants to only invite 3 of his siblings. He has 15. He came from a huge family and grew up Mormon which he's ex Mormon and actually hates Mormonism but that's a conversation for another day. He doesn't talk to a lot of his oldest siblings because one is a pedo who molested on him and his two other sisters and the other older ones he just doesn't talk to because they have nothing in common. He's not invited the younger one because he's never met them. His youngest sibling is 10. When he found out his mom was pregnant again he didn't even message his parents. His relationship with his parents is pretty strained. He's not inviting them because they would want his younger siblings to come and he has no relationship at all with the younger ones. So out of 15 siblings he's inviting 3. I feel like this is all going to come off really fucked up. I understand not inviting the pedo and some of his siblings still support the pedo. Makes sense. But maybe to just be nice we should at least try to invite more. He said he's not having a wedding to be nice. He's having a wedding for us and these siblings are who he is inviting. I'm probably overthinking this. He's not really close with a majority of his siblings and it's his family. So maybe I am just overthinking this whole thing
