After some adjustments, I see a low-pass branch (C3, L3, C4), and a
more complicated fast band-pass branch ending in (A). The idea makes
sense, and C4, the element that is slowing down the low-pass
branch, can be eliminated. But the design of this complex circuit
would be complicated. The symmetry that allows a direct design
with identical branches doesn't exist in this circuit.
The primary waveforms required for the two different branches are
different, an so they can't be independently designed and combined.
An approximate design with similar primary circuits, followed by
some tuning, may work, but I am not sure if an exact design for
complete energy transfer is possible with different branches.
But this is an interesting idea to investigate.
