Hi Me, 
        The current differences in parallel transformers is not going to create
a problem. HOWEVER, the output Voltage differences may well cause difficulties.
Most MOTs are in the 2kV-6kV range, while NST are 9 kV to 15 kV, and flybacks
are usually 10 kV to 35 kV. 
The secondary of the lower voltage transformer will appear as a load across the
higher voltage one. With two mis-matched transformers, his results in (V1-V2)^2
/R being dissipated as heat inside the transformer. With three transformers,
the formula is more complicated but the result is more internal heating. 

Hope this helps,
