Overseed questions on established grass

Sorry for another "overseed" question.  I did a search and didn't find my answers.

 

I have an opportunity to rent a 65 acre field that is established with a mix of various grasses (brome, timothy, fescue) and a fair amount of clover.  Prior tenant said "not much clover in first cutting, but latter cuttings have 40-50% clover".  

 

I'm not a fan of clover.  I was wondering if anyone has ever terminated the clover in a grass field (spray it with 2, 4D or Dicamba) and overseed with a grass to fill in.  Perhaps overseed early in the year, and spray to kill the established clover mid-summer?

 

Thanks
