I went online to the WDW website and chatted with a CM. She specifically stated that only guests on the reservation for CL access are allowed in. I asked if the room capacity were 4, but only 2 guests in the room, could you bring in 2 non CL guests (who were also staying in the hotel) into the CL. She again stated no, it is not allowed, only guests registered in the room with CL access were allowed in. It may be a moot point anyway, since they may not even allow you to add it on. Disney only does it when CL rooms are not completely booked or the number of guests in CL rooms is low. If you go online and see CL rooms available to book for your dates, then you may have a chance. Also look at the difference in room rates from what you booked (with no discounts), that will be about you will pay. They are not giving it away at a bargain price. And contrary to what you are saying, you are trying to cheat the system. Also, Disney does tell people in scooters they have to get out of them to ride certain attractions - Pirates for example.
