Something very much like this has been done in the game of like
automata. It's called the "unit cell":

There's also a variant called the "deep cell" which allows you to
simultaneously simulate two independent versions of the game of life on
the same meta-grid. This lets you create a hierarchy of unit cells
while also being to simulate other patterns at each of the levels at the
same time.
