I think it's a good idea to blend out obvious steps in the ports and this implies making sure the outlines line up more or less. I would always by preference remove metal from the component which is cheaper and easier to replace!
I've come across a few slavishly polished manifolds in my day but am not convinced that they bring much real benefit and they must take many, many hours of work to produce.
As far as I can fathom A7's seem to run perfectly well on absurdly narrow inlets and exhausts, so I wouldn't expend enormous effort making them bigger either. What you've done there Jon is as much as I would.
Just my opinion!
