I think your idea with capacitative coupling with inductors to tune out
the reactance would work fine too, but I haven't tried that.

If you do try that, I recommend keeping the Q as low as possible.
Otherwise, voltages will get very high, and you might well end up with
greater loss as well as other problems. Minimizing the Q means keeping
reactance values low which in turn means making C as large as possible.
This leaves you with less reactance to compensate for. In other words,
don't make the C small and try to compensate for the large amount of
resulting reactance.
