Actually, in a somewhat different way, it was:
http://www.coe.ufrj.br/~acmq/tesla/mres6.html
But this design produced inferior results, in comparison with
a conventional coil with the same resonator and power supply:

The reasons are probably the lossy C2 capacitor and a design for
smaller voltage gain.
You are right in saying that magnifiers, as usually built, are
not better than conventional coils. A capacitor in parallel with
the secondary coil is essential to make the difference, that is
practically just faster energy transfer.
