I think you are severely underestimating Botham and Dev. Might as well leave Waqar and go with just Imran and Wasim since they can do everything he can. Two is necessary if you are making Imran bat at 7 especially, but well, Akhtar isn't even better than Botham and Dev as bowlers.
Breaking down mid game would still be an issue, as will be over bowling. With just 4 bowling options, it can turn ugly real soon. You need a 5th option really, and Yousuf isn't even a good fit for 6.
You made 2 teams. Firstly, had Akhtar there to get 5 bowling options forcing Imran to bat at 7, and he isn't even a better bowler than them before even going to the additional 30 run batting. And in the 2nd one, you added Yousuf, which just leaves you with no 5th bowling option, absolutely none. Over bowling your pacers might soon turned into a very serious problem there. Not to mention Kapil and Botham will be useless with the ball is just wrong. In the Pakistan All Time exercise, Mushtaq Mohammad close to unanimously made the team. Kapil and Botham are really no brainers here.
