Hi again Kirk.
I can now welcome you officially to the Anchorage.
From what you say I think this format of the game will be right up your street.
In several chats that I have had with Andrea the Games Designer, it is clear that he does not mind anyone modifying his rules system to suit their own perception of the historical reality as they see it.
As long as you and your playing partners agree to the changes and you enjoy the game it really does not matter at all.
Any questions you may have will find an answer here from one or another of your shipmates.
May you always sail with a fair wind and a willing foe.

Rob.
