It doesn't appear so. In order for the two to work together they have to share at least one frequency. The DJI frequencies are: CH1-5705MHZ, CH2-5685MHZ, CH3-5665MHZ, CH4-5645MHZ, CH5-5885MHZ, CH6-5905MHZ, CH7-5925MHZ, and CH8-5945MHZ. The FatShark frequencies are: Ch1-5740MHz, Ch2-5760MHz, Ch3-5780MHz, Ch4-5800Mhz, Ch5-5820MHz, Ch6-5840Mhz, and Ch7-5860MHz.
As you can see, there are no frequencies in common.
