Go for it, as others have said, have whatever you like in your own home!
We live in a 70s house and someone had added a dark wood dado rail up the stairs. Since then, someone has added a handy rail up the stairs, so it doesn't really look right.
The hall/stairwell needs decorating, but to get rid of the dado rail would mean a lot more work, so we may have to just live with it... but if it was part of the living room, that would be different!
