You'll have to make a new component no matter what, but all you have to actually do is:

copy-paste the original component
edit the name, size, cost, pic, whatever
add a new tech requirement: whatever the racial tech is.

If you want the component to be available from the beginning, you could make the first tech level really cheap.

Sure, the normal components would still be there, but hey, they can waste space on extra-large bridges/lifesupport/crew quarters if they want. Not practical, but possible. It could be for alien crews, from captured populations, too.
