I know you want to increase the flow to a extent, but if you remove too much material and speed up the flow by too much your end result would be worse than what you started with.

Making the passage bigger would slow the fluid speed(mph) down if the flow rate(Gpm) remains the same. I have no idea if faster flow coolant is better or worse compared to slower coolant with more contact area.
