Advice on bringing up father/daughter dance

Hi everyone, really enjoying all the posts and conversations on here and would appreciate some thoughts on something I'm not sure how to handle. Our wedding is coming up and my FMIL is pushing the father/daughter dance mostly because she wants the mother/son dance and is a bit traditional. She's an amazing lady but this is a little uncomfortable for me. My dad is my best friend and I love him dearly but neither of us are very emotional. My mom passed away when I was 17 and long story short it was difficult. Anyway, I just don't know how to ask him if he wants to do the dance thing......he has 60+ tattoos, is already gonna be uncomfortable in a tux, and he won't know anyone there due to it being an out of state wedding as FH has way more family than us so we're doing everything in their state. I told FMIL she can have her dance with FH if we don't do one but she wants me to bring it up. Ughhh it's difficult not having a.....conventional family. Any help would be appreciated, thanks!
