While your room is just about perfect for an 8 footer its is cramped for a 9 footer.
My 8 Footer sits in a room with similar dimensions (scaled) and it has a similar obstruction near one corner. In practice, you (the owner) get used to not leaving the CB down in that corner and almost eliminate the need for a short stick.
You can use it to your advantage when "friends" come over and then leave the CB in that hard to shoot corner. You won't feel good about a safety played down there, BTW.
