No. I want to know if a plumber who was called in for a backup would squeeze himself through a 24" base cabinet to access the actual cleanout where shown and if there was room for him and a cleanout snake.
Your question at the end sounds like you want to install a toilet on that cleanout, and not add another cleanout above it.
Huh? I wouldn't do that. Cleanouts are necessary. In a condo you cannot remove something that other condo owners are expecting to remain in place, as common shared property.
I'll let Master plumbers comment from here on.
