I like your idea.
Lets have a crack at this.
200 each session.
Play 3 sessions.
Score 600 quick fire runs.
They will have 350 to chase.
We will fold them in 1 session.\
We will fold them within 270 runs.
Bangladesh will win by 70 odd runs, thus taking revenge for the first test as well.
Series squared 1-1.

Then which of the favors of your Lord will you deny? "We do not deny any of our Lord's bounties/favors upon us."
