Is it possible to play the Scenario with the first edition of the game (I own all expansions)?

I do love AGoT, but it rarely hits the table since my group isn't that big, so that getting the second edition is not an option for me, but I was curious to see if this Scenario, maybe with some small change, could be played with 1st ed.

Thanks for help

Yes, easily. The 2nd edition rules are available online or you can stick with 1st edition if you want. It is really just a variant on starting positions plus new cards to use for the different houses.

Balance wise, you'll probably want to turn that 3rd siege engine into a knight - 3 siege engines are too much and cutting down to 2 + bumping up to 5 knights was a good fix for 2nd edition
