This is just a small point. I may have missed it, but if we said that having an independent come to present amendments and to vote were to happen, that person could only replace someone sitting at the table now, because you're not going to change the numbers: the numbers are allotted. The government has six members and the opposition has five. It's inconceivable to think that the government would allow six over there because of amendments.
If you're talking about giving an independent the right to vote, with one of you willing to give up your right to vote, that's a whole different story. But sneaking someone else in to even the numbers simply won't work.
