TV flyback transformer cores are too small to handle
much power.  They saturate too easy.  The air core
Tesla coil is immune to saturation, allowing it to run
at very high power.  Perhaps if you used a bigger
ferrite core, you might be able to wind a bigger
flyback, but it still won't be in the same league with
a spark excited Tesla coil.  Marco Denicolai is using
some big Phillips brand cores in his HV switching
power supply, and they seem to work fine.  I bet they
cost a lot though.

Except for Marco, I'm not aware of anyone on the list
working with high powered ferrite transformers.  Wish
I could be more help.
