Austin Powers 4 idea

well, we all know that if there is an austin powers 4 its going to be pretty much full of rehashed jokes like the third one, so i figured what the heck if theyre gonna be rehashed, might as well have fun with it. how does this sound for a basic plot. Of course this time they have to travel to the 80's for some reason, but why not make it the late 80's going into the 90's. Since he has to "fit in" to the era, why not have him go undercover dressed in 80's/90's attire, such as make him look like wayne from waynes world lol. everything except the waynes world hat. while he's back in that time he should have a random run in with the real wayne and garth, which shouldnt be a problem since he acts as dr evil and fat bastard at the same time. I think it would give that sense of finally bringing the duo back to waynes world fans. of course if he has a run in with them the time is going to have to be in the 90's but i think it would be pretty cool.
