Noise is coming from other sources than the TMCC and buffer outputs, I get it, so ratio does decrease.

If you'd share your educated guess for a simple inductor choke value (and a part number?), I'll get one and try it. This was my uneducated guess a couple of days ago: peak impedance is at 4.1 MHz, in the lower part of the DCS range. Realize from Adrian's "dissertation" that some aspects of DCS signals have frequencies in the TMCC range, so if those are what is being interfered with, a choke won't help that part. Maybe that line of thought would lead to a choke value in a lower frequency range, closer to the TMCC's top end, though?
