Father of the Bride/father of the Groom toast? ?

My fiancé and I are paying for the majority of our wedding but both sets of parents are contributing a generous but equal amount to our funds. Should we ask both the fathers if they wish to do a wedding reception toast?

At my older sisters wedding, my father gave a toast and it was very important to him. But they also contributed the majority of the funds for her wedding. My fiancé and I are at a different stage in our careers and also wanted to maintain control over planning and guest list so while both sets of parents want to contribute, we will be covering most of the cost.
