I might take this route for the front and see how it plays out since I have the same setup currently.

I have basically the same van and did a brake swap this year. The difference has been amazing. My van is a 2002 Quigley E350 V10 RB with the GM based Dana 60 front axle. I swapped to 2010+ Dodge Ram 14" rotors and calipers. Everything else is the stock Ford brake system. I didn't know the van had functional ABS until this swap. I was nervous doing a panic stop test above 60mph. I wasn't sure what else would break with that size vehicle...
No affiliation. Customer service was lacking. Delivery was slow. Fit was eh. I had to do a little grinder modification to fit.
Everything else I got from Rockauto or the local suppliers. I want to say all in, the cost was something like $650 plus new wheels and tires.
