New guy; brisket and turkey

This is my first post. Have had my XL BGE since July and have had generally good results thanks to the great information available on this forum. Thanks to all. I need some advice. On Christmas, I'm cooking a 6# brisket and a 11# turkey with hopes of completing them about the same time, late afternoon. Original plan had been to start the brisket around 3 am at 225*. After the brisket had passed through the plateau, I planned to put the turkey on the grill, have room side by side, and raise the temp to 300-325 until the brisket hits 195-200 and the turkey hits 165* breast/175 thigh. After reading a post about the 5 hr brisket cook method, I decided I needed advice re the original plan and this 5 hr method. The 5 hr plan would allow me to cook the brisket first and then the turkey in about the same time, except the brisket could be resting while the turkey cooks. Appreciate replys on which would be best. Thanks in advance.
