Gap produces noise in >100 Mhz range but total power
radiated (or far field EM wave energy per bang) is
really a miniscule with respect to a total TC power
used.
If you think that primary tank noise is dominant noise
you may be quite wrong.
When TC output arc continiously hits any grounded
circutory,object etc,the radiation noise increases
much above that of primary tank.
But even then total power radiated isn't comparable
with total output power.
Problem I see in a frequency range.Gap produces higher
noise freqs than secondary hard strikes and
interference with TV and other sensitive receivers    

working in that range is something to be considered.

More energy dissipated in primary tank and more energy
dissipated in gap->more current zero crossings in 
gap  ->more (re)fireings of primary arc->more short
waves produced=Mamma cannot watch TV.
