However you want to do is ok in my opinion but generally speaking make is that a character the character sheet is not so restricting you don't give player a choice which a good thing. However, Oh boy your concept is a bit taxing for me, but then again I was never into ship maneuvers and stuff like that. However, I can see that ithe system is detailed which is good and avoids conflicts. However, it does not allow for modified ships . I really think that would be super cool, but it break the system so that is up to you As others pointed out I do not see this as getting so out of hand you would need help with your GMing. Another thing I would like to say is please check your grammar and spelling (I appreciate it).
