But for receiving it would be possible to use the code as it is. I'm thinking of connecting the data pins of two receivers to one Mega pin through Schottky diodes. They have a low voltage drop and acts as an or-gate which passes the data without disturbing each other.

This does not work correctly. In the absence of a signal, the receiver receives noise. With the combination of "or" two receivers interfere with each other.
