If you were the author/creator & wanted your favourite character to win

If you created GOT and wanted your favourite character to win the Iron Throne and become King/Queen of the 7 Kingdoms;

1: What would you change? Small things? Big things? A mix of both?

2:Who would you kill off or keep alive?

3: Which character/s and/or Houses would you have your favourite character ally with?

4: Which character/s do you hate and want to give a more gruesome death than they may have gotten in canon?

Bonus: If Daenerys is your favourite character, would you still have her go mad like the rest of her ancestors or would you have her “beat the genes” so to speak?
