Soil stack out roof

    My house has an ordinary soil stack - from manhole just outside, the pipe runs 1m or so into the house in clay then straight up and out the roof. It’s serving only the bathrooms upstairs.

    Q: could it be trimmed under worktop height upstairs and replaced with an AAV? This would be handy as would eliminate a boxed corner in one room and the protrusion through the roof.

    many thanks!
