but when the OP played the "senior engineer" card, I lost most of my hope for this being a reasonable and honest project. Maybe I'm just pessimistic, but it seems like a fictions entity to (A) shift blame on to someone else, and (B) Restrain project flexibility to what the OP wants, regardless
..sorry i forgot to mention that the senior engineer concerned is probably one of the top engineer/scientists in the world in this subject.........just thought it relevant to bring this in, to kind of instill that this isnt some start-up staffed by clueless jacks.....the only clueless jack there is me.
Here is the system.....your commects on power factor are very good all of you.
Here is a
block diagram to remind us:

.......The twisted pair bus carries AC volts and current........i am wondering....
.....what is the power factor likely to be?
......do you agree that the fundamental of V & I are in phase?
.....How would you correct the power factor?
......why would you think correcting the power factor was wothwhile?
........Do you think that correcting the power factor will significantly reduce dissipation and thermal heating in the 50KHz current source?
(BTW, the 50KHz current source is mains fed, and , as you know, its INPUT is power factor corrected, as demanded by the regulatory authorities....though i here, am speaking of the power factor in the OUTPUT of the current source, and the regulators dont care about this as you know)
This system is waterproof and thus good for "remote operations in wet places".......and the regulatory bodies are not going to be concerned about emissions from the twisted pair.......(and if they were bothered, they'd be told to "butt out")....
just put a 10μf cap in parallel with the output and an inductor in series before it. This gives you the cleanest output.
....that was the first thing i did.....put the said L and C as you describe.....but the senior engineer told me to get rid of the LC filter, because he said that the current waveform was "very smooth"...........his very words..."things are very smooth here, get rid of your inductor"
