Clearing all the content with 2 player?

[Saytrick]

Hello, me and a friend of mine recently started playing, me as a thief and him as a cleric. Now Assassin and Bishop respectively, we are level 45. What we are wondering is if it's possible to clear the whole game with just the two of us? Thanks!

No. You cannot complete end game bosses.
