Family trip from KY to WI, wanting to negotiate with dad on stopping in KS any ideas on how to make it work?

Hiii, so im in KY living with my dad and our family is going to WI for a family reunion, via car. BUT, im going to KS to visit with my boyfriend for a couple weeks before- i just moved from there earlier this year due to family issues w mom.

I wanna try and merge the trips, like I fly out to KS and stay with him for our time, and then we both come with on the way to WI so he can come with me and we can get some extra time together + meet my extended family!

However, The drive from KY>WI is about 10hrs. With stopping in KS its 22hrs ... which is over double and I don't think my dads willing to do all that driving. Any ways we could work with it or any ideas to negotiate with the trip, me and bf can both drive but neither of us have cars. Flying directly from KS>WI is out of the question, too expensive but we do have SOME money. We're just trying to think of ideas, so anything helps
