Change of City look

I've purchased a few KR tile sets, one for example is here https://store.steampowered.com/app/1710061/RPG_Maker_MV__KR_Urban_Modern_Tileset/
I have also the school one, shopping spree, interiors, was interested in buying the truck stop one also.
Shall I update the city to this Tileset? To move away from the standard RPG Maker MV stock set? And eventually move over the other graphics where possible.
This will of course take time, some buildings may change.
Or it could be something I wait to do for beyond V1.0?

Looking for Supporter's insight :), Thanks, - B
