Antonio,
has the following topology ever been tried:

                                              (=+=)
                                                  I
                                                 L2
                                                 L2
-------L1- +-------+-------------)   L2   (  EIP1
                I          I                      L2
 PSU     C1       SG1               L2
                I          I                       I
------------+-------+-----------------+-------------GND
Description:
The electric induction plane EIP1 is a metal plate with hole in the middle
wide
enough for L2 to stand within the enclosed space without touching; it is
connected to L1, C1 and SG1 the spark gap, it  not connected to L2 the
secondary coil other than by capacitive coupling.
L2 is grounded at one end and connected to a toroid at the other.

Would  it work?
