Using slightly staggered rims for a square tire setup?

I have 8*19 and 8.5*19 rims currently with a staggered 225f/255r width setup. I am wondering if there will be any difference in feel if I go to square 255 f/r setup next while keeping stock rims vs changing out the front rims to match the back. The tires I want should fit both size rims in the 255 width per manufacturer.
