Sure its possible.

Please see the holteck ics.ht12d and ht12e there is a preamble in the data transmission,at receiver this preamble is matched.

Swapping the preamble at tx and to set of rx with different preamble is what you require.

Coding is possible,first let me know you are ok with this idea.
