How to include my father in our wedding..

A little backstory..


My dad has in/out of my life for my entire life, and I was lucky enough to have my grandparents to raise me. I came out to him as gay my junior year of high school, which didn’t go very well. He made his comments, and we didn’t speak much over the following 7 years. He is about three years sober now, and over the last year and a half we have started to rebuild our relationship.
My dad has become my number one fan, and for the first time in my life is someone I can count on to talk me through anything. He has met my fiancé a few times now (he lives in another state and we do not have the opportunity to see each other more often) and of my small family, he is among the most supportive of my relationship.
My fiancé and I are much more close with his family. His parents have offered to pay for our wedding and have been nothing but supportive of us. We have asked my FFIL to officiate our wedding, which he excitedly agreed to. My FMIL is helping me with the planning, and I am trying to include her in all the planning I can to show my appreciation. I also plan to get her a very special gift (tbd on what).
The other day my dad jokingly asked me if he would be included in our wedding, and I panicked and told him I would like for him to be, which he responded that he would love that.
I honestly have never considered either of my parents being a part of my wedding, due to the years of no relationship with either of them. I have also always felt ashamed of my side, because of the differences in lifestyles between my parents and my fiancé’s parents. His are very traditional and are much more involved in his/our life.
I have a similar relationship with my mom, as I do my dad, but she and I don’t talk as often. My mom is very supportive of my relationship, but she has her life in California and I have mine in NC/AL. We talk occasionally, and things are mostly fine between us. I intend on having a mother/son dance with her at our wedding, which will be my way of including her. However, I am stuck on my dad. It means more to me that he is included in our wedding, than my mom, but I have no idea how to include him. With the healthy way our relationship is growing, I do want him to have a part. I also know it would break his heart to not be included, especially to end up seeing my mom included.
My grandmother will be walking me down the aisle. We both have our wedding parties chosen and I don’t really want to have him as a groomsman.
Any advice/thoughts would be greatly appreciated.
