You don't need a mixer. You do need somebody to make up an adaptor
cable to connect the two transformer outputs to a stereo mini-plug
for the MD recorder.

Yes, it boosts the inherent mike noise, but chances are the
recorder's preamp noise is the dominant noise, so the transformer
gain before the preamp will give you lower noise overall.
>Q: Do the transformers and mixer also introduce noise into the system?
The transformers, no, transformers, like parabolic dishes, are "free
gain." The noise added by a mixer would depend on the quality of its
preamps; with a mixer you'd skip the mike pres in the recorder and
use its line input instead. I'd try the direct connection (mikes,
transformers, recorder) first to see what improvement you get that
way.
