Should older maps be updated to use Donut3 coloured and non coloured walls?

Yes, i'd like this.

As a completely adjacent suggestion, i'd also love if wallpaper was purchasable. Currently colored walls are just turf related. For simplicity, it should be like that for round-start station walls. But new builds could have the ability to turn walls these colors too, by slapping them with aforementioned wallpaper.
