I was just thinking that it would look really weird in different widths.

when the boards are that wide, the difference actually shows very little when theyre next to eachother. At least the 10s and the 12s. The 8s obviously look smaller.

Then switch the 10 and 12 which are next to the 8 and you will have 8, 10, 12? *Not counting the leg of the room.
