You don't have to do it stop doing the main quest as soon as you find Sky Haven (the quest Alduin's Wall) and concentrate on just the quests for the Blades Rebuilding the Blades and Dragon Research then theres only the repeatable Dragon Hunting quest left for them. When your ready start doing the main story again then during the quest Season Unending they should approach and ask you to kill Paathurnax say no and keep going with the main quest when its over the the quest Paarthurnax should soon vanish from you journal.

If you complete the civil war and Season Unending doesn't happen they could ask you to kill him after Alduin's Bane. Some people have said they were asked earlier but its worked on at least three of my characters (all the ones i did the main quest with), that might be down to Delphine so maybe avoide her as much as you can.

On the PC there are a few mods that give you a way of saying no without the Blades hissy fit (none to lock the Blades away like Puggles suggested though).
