I think your biggest concern is fitting it under the lid. I suggest putting the lid on and measuring to the grate from the lid vent and checking that against the size of the turkey. If it doesn't fit, you can always spatchcock the bird but then you may be constrained by grate space. If you have (or can borrow) a second kettle you should be good to go. This is also one of those places where the 26" Kettle really shines!
I plan to use my rotisserie this year. I did a trial run with a 12 pounder yesterday and it worked well.
Done in 2:10 at a lid temp of 300°F! I used apple and cherry for smoke wood and that gave it the mahogany color without an oversmoked flavor.
