I must replace entryway flooring in my Georgian home because of insect damage at the entrance. It is unlikely I can match the engineered wood that was installed 30 years ago.

Since I have THREE distinct surfaces visible together --slate, wood and carpet--this might be an opportunity to remedy a design flaw. Should I replace the entryway flooring with slate (assuming I can find the 10 year old slate tile) for a continuous surface to the back of the home?

If I kept hall flooring wood should I replace the adjacent LR and DR carpet with wood? What about the stairs?
