If you move the secondary out of the primary, the coupling
coefficient decreases.
The other resonator has almost the same inductance of the larger one,
9.14 mH. Gets close to the fast mode 4,5,6, that requires k=0.281,
but a lot of capacitance at the top of L2.
(See the table at http://www.coe.ufrj.br/~acmq/magt2.txt)
I would try to keep the high coupling coefficient, to get fast
energy transfer. With L3>>L2, what happens at the low-impedance 
secondary coil will not be very significant. I think that only the 
main tuning relation L1*C1=(L2+L3)*C3 would be really significant.
I have updated my MagSim program so it can generate a table of
component values for the various modes. I still have to make it
generate the waveforms more directly. The program is at:
