Can I throw my own "bridal shower"?

...or maybe more like a bridesmaid-get-together, but still.

I would love to host a party for my bridesmaids and have them get to know eachother and get into the wedding mood (before the bachelorette party, which I obv won't be arranging myself). I don't think I really want an actual bridal shower, with gifts and more guests and all, I just want to have a smaller party with my bridesmaids.

I thought we could play some of the usual bridal shower games (like guess the dress and toilet paper dress making), make mini wedding cakes, have some drinks etc. Would this be okay for me to arrange/host? If yes, I would love suggestions for some activities! :)
