I hate to be the crusher of your dream, but do you think you would be capable enough to actually handle everything that would require of you?
All the huge amount of paperwork, requests for supplies, cost estimations, wages, socialising with all the shipgirls (and be competent at it), leadership skill and cool enough of a mind to plan on the go during combat and battlefield situation and so on?
Oh and be mentally prepared that some of the shipgirls may, in fact, die.
