Wedding vow renewal ceremony after 5 years, what do you think about it?

The most important thing first: I love my husband and am grateful every day to have him in my life.

There is only one point in this relationship that still makes me sad: our wedding. The decision to get married came quite spontaneously, even though we had already been a couple for 7 years. Because of his culture and family, we decided not to wait long and planned the wedding within 2 months. The family is large and I didn't want a wedding with over 100 guests, half of whom I didn't know. My now-husband also knew that his mother would get too involved if she had enough time.
Looking back, I know that I stressed myself out too much here and hardly paid any attention to my feelings. So we chose the first best location, the first best dress, the first DJ and I realized too late: it was all happening way too fast for me. I'm really happy about my marriage, but I always imagined my wedding differently. But I actually had everything: rings, dress, DJ, cake, location, 50 guests and even a first dance. But looking back, many moments make me very sad and I still can't process them properly even after 2 years. For example, his family didn't like the fact that my husband took my surname. We didn't communicate this much because he knew how his family would react. This was discussed loudly over and over again at the entire party. My sister told me: I have to forget these stupid comments. But I find it very difficult because I don't understand how you can behave like that at a wedding. Unfortunately, there were still a lot of comments about me and my family. I heard too much of it and I cried a lot after the wedding. My husband was very sad himself and was expecting a lot, but not this. Since then, my relationship with his family has also been difficult and I realize how I blame myself (which I don't have, I know).
Last week I openly told my husband that I had imagined everything differently and that I love him very much, but that I had wanted something else for us until today. He reacted very sweetly and asked me again if I wanted to marry him. But now I'm wondering, because I already had a real wedding in the eyes of all the guests, can we have another celebration? My husband says it would be possible in his eyes after 5 years. I think it's a really great idea, I would love to have my dream dress and also the walk down the aisle (we didn't have anything like that). But I'm afraid of the reactions of others? My friends think it's a great idea, but I think that's only because they know how I felt afterwards. My husband would do anything to make me happy. I give him a lot of credit for that and I have to say: the second proposal made me incredibly happy and I would definitely like to organize another wedding. I also like the idea of involving our child. He would be 3 years old at the time and would of course play an important part. But I ask myself:What do other people think about an invitation like this? I don't expect any presents, but how do you say that you still want a second wedding after 5 years? My parents don't quite understand why I need all this either. They see it as a waste of money. They love me, they would go along with it, but i know: For them its too much. Also, I already had a wedding dress, would it be okay to buy a new one (which I like more)? It's totally crazy, but it makes me really sad not to have chosen the right dress for me. Can anyone understand my thoughts? What do you guys think about the situation?
