Hi Megan
We did this a few years back when we went from 2 houses to 4 houses. It was very successful (we knew we were not going to budge some of them if we had to move them to a new house ;))
We started the whole process again which gave us the opportunity to completely overhaul the houses/motos/names and distribution of the house numbers.
Even down to making sure the names were of similar length in name/syllables etc
They are all very house-proud now! All the best!
