BLE and NRF24 protocols simultaneously? (nRF51822)

Question

Is it possible for a nRF51822 to communicate with a NRF24x device and utilize BLE simultaneously? 
 In essence a type of dual mode?

"The nRF51822 is only able to run one protocol at the time (what we call ‘non-concurrent multi-protocol’). The way nRFready Desktop 2 works is that it will alternate between trying to connect to either a Gazell host or a BLE master, and as soon as it is successful on either protocol it will enter a connection and stop using the other protocol."
