Conner and fitz for diggs?

Should I trade James conner and Larry fitz for diggs?

My other option which is a reach would be conner and fitz for Fournette
Or conner and tevin Coleman for Fournette

Im in a similar boat figuring out his worth, but I believe fitz and diggs are too similar to make that first one worth it. If he would give up fournette Id take it
