Wedding party not involved in ceremony

My fiancé and I are doing a bit of a non-traditional wedding-no cake (we don’t like cake), no bouquet/garter Toss, and more. Another idea that I’m tossing around is our wedding party. Originally, we were not going to have a wedding party at all, but now we have decided to have a wedding party so that we can have our near and dear family/friends participate. However, we are letting them dress how they want-preferably using a color from the wedding (neutrals, navy blue, and pops of sunset colors-so a lot of choices). I want them to be apart of our special day, but my dilemma: during our ceremony I would prefer just my fiancé and I standing at the altar. I don’t even want the wedding party to walk down the aisle.

I do want to announce them when we make our entrance to the reception though. Plus, have the party on our website displaying who is whom. Of course, I will get them gifts and have a really cute proposal idea for the bridesmaids.

Am I overthinking this or is this doable? No wedding party involved in the ceremony, yet involved in the reception and other aspects.
