I am not sure about Gold, but I assume it is still there. IN the designcreation.txt I believe there are two lines which stipulate the size hull with which to use the design. If you delegate the design to a larger hull, then it will obviously only be able to use it later in the game. Then it depends upon when the new colony ship hull becomes available as to the time of use.

Just make a new colony ship hull, slightly larger, have it come available later in the tech tree, then set the design to use only hull of that size. Sort of indirect way of doing it....that is if it is at all possible.

Just an idea, and one you've probably already thought of.
