A new NT 20 or 30 would need 2 holes of approx 1 1/2 inches each located 12-16 inches off the floor. The existing holes would need to be patched. This would free up the riser space that the current inlet? tube uses. Also it would allow for easier on trip repair.
Now is the time to do it, not after you get the kitchen put back together.
Just my $.02 worth.
I have some sources that I have been pleased with for this sort of thing if you need them.
