For a CW system, yes, as VSWR works as the Q of a lumped LC resonator.

For a capacitor-discharge system, the VSWR works only as a measure of the
losses in the resonator (as Q again). The higher, the better, but not much 
is gained after some point.

I don't see physical reasons for any additional voltage gain based on 
transmission line behavior of the resonator, when compared with lumped
LC behavior. Some experimental evidence?
