It's a good or bad ideal?

Im sorry but you have to give us a better diagram of what you are trying to do. To me it looks like a bad idea but then again i have no clue based on that picture.

You will flashover that transformer(12v-220v) and kill it dead if you hook the 8000v source to the secondary. definitely a bad idea.

From what I see, the 8kV is going into the 120V winding. I think that you might kill the 8kV supply if it can't handle shorts because the core would have it's V per turns way exceeded. This causes saturation which makes the coil look like a resistor with the resistance equal to the resistance of the windings (this depends on the frequency though). Is this right?

Also I wouldn't suggest you using HV with alligator clips so close to each other because the insulation is usually only rated for 500V.

no it go to 12V winding

That still will not work. The transformer is not built to withstand more then 1000v so 8kv across the 12v or 120v winding will instantly burn the transformer up.

At the designed frequency (50/60Hz), the 12V winding won't take much over 12V, then the inductance decreases to the point the transformer will draw as much current as it can.

At a higher frequency it will take more voltage but as you get over a few kV on the output (previously primary) winding, the transformer will get destroyed by flashover.
