Full Duplex Wireless, as in transmitting and receiving at the same time ?

Not at all easy, the transmitting module will interfere with the receiving one.

Perhaps explain what the project actually is and exactly why you want full duplex ?

Yes, very easy if you use the built in UART, Softwareserial will not work it is a simplex implementation. To save a lot of greef get Arduinos with two serial ports (UARTs) built in such as the MEGA.
