Big problem. It simply won't work. You see, neither Dragon nor Dragon

than a hollow tube to which the solar arrays are attached. Everything
that's in Orion's service module is *inside* Dragon and Dragon V2.


Can't you put bigger tanks (instead of cargo) in the trumk for extra
fuel and ECLSS consumables?


No.


If needed, how hard it it to make a longer trunk to accomodate move
volume needed for extra tanks?


You need a real Service Module if you want to go outside LEO.
