Old Chief - Single Player Levels

I know new Single Player levels are constantly requested, but this is with an add on. I did not come up with this idea, but if ever SC chooses to ad another few levels the last level could be 'Old Chief'.

At the start of the game (start a new account) the villager refers to the 'Old Chief' and that we are the 'New Chief'. Well... How about much later in the game we encounter the 'Old Chief' in the Single Player level - it could be the last level. And that he seeks revenge, and has plotted with the Goblins. SC could incorporate a thrilling storyline with all the Single Player levels linking together. And the 'Old Chief' as the boss. But not too much like Boom Beach, just that the 'Old Chief' influences some levels.

If anyone comes up with anything to add on to this idea, pop a idea that we can add to this one. I feel that I have only addressed the tip of the Iceberg.
