Basic silver Columbian is not too complicated, so if that is what appeals to you, give it a shot. There is no disgrace in failure, should that occur, but if you don't try you will always wonder. I don't know of anyone else who has worked on Columbian in Ameraucanas, but there have been Columbian Leghorns along with a good number of other breeds. It sounds like you have a good handle on Mendelian principles, so why not? Good luck!
