Exactly, there isn't enough time to charge the tank cap in (1/40000) seconds
(the time of each half cycle).

You could do that, but you'll have to keep the spark gap from power arcing
(shouldn't be too hard with an air blast)

Don't know, you could try it!

These transformers would be good for making a HV DC power supply.  The high
frequency lets a voltage multiplier work much better, because there is less
time between charging cycles, so a much smoother output.
