With just 7V to work with, a cascode MOSFET CCS would require a negative PS. What's the bias current? For current less than 10mA I would recommend a cascode NPN BJT CCS. That too would entail a negative PS. My system has 16 long tail pairs; so, I have some experience with CCS tails. IME the higher impedance cascode CCSs are sonically superior.
