No, downloading the SoftDevice is not required when running proprietary radio protocols such as Gazell.

I believe this is the implementation of the radio library for MicroBit:
https://github.com/lancaster-university/microbit-dal/blob/master/source/drivers/MicroBitRadio.cpp

Looking at this code I see that it has nothing to do with Gazell.

Instead this is a very low level RF protocol implemented on top of the RADIO peripheral, and does not include Gazell features such as auto ACK, ACK payload, frequency jumping, multiple pipes etc.

In other words I would not recommend using the Gazell library in the nRF51 if you want to interface to the MicroBit.

Rather I would try to port the code from the link I included above to run on the kit.
Since most of the code is accessing hardware registers only this should be relatively straight forward, but you would need to change the code interfacing other MicroBit support libraries.

The radio receiver example in the nRF5 SDK v12.3.0 can also be used for reference:
\nRF5_SDK_12.3.0_d7731ad\examples\peripheral\radio\receiver

Btw: Should I download the softdevice?
