There has to be a RA(T) surely. Otherwise see-and-avoid goes out the window (that a pun or oxymoron?)
Seriously, whether in the open FIR or in central belt class D, it'd be impossible to operate with these things. At least with Police 51 (EC135) we know where we are (and them as well).
Daft idea. Hopefully Strathpol will wreck them on training exercises.
