Yes anything is possible - but the ENTIRE point of a Tesla coil is the
use of a term called DISRUPTIVE DISCHARGE. This is term that Tesla
himself used quite often.
this term is largely left out of the description of Tesla coils - but
not usually forgotten by enthusiasts.
The main reason that Tesla coils work the way they do is because they
store energy over a long period of time (eg. 1/50th of second) and then
discharge it over a short period of time (eg. 1/30,000th of a second)
through a spark gap or mechanical or electronic switching - hence the
term DISRUPTIVE DISCHARGE - the frequency is really irrelevant - except
for the fact that Tesla coils are usually designed to be of practical
sizes for the backyard scientist to be able to build and/or afford.
Some of the benefits of storing energy over a long period and
discharging it over a short period of time is the ability to harness the
effects of massive peak currents (and the resultant magnetic fields that
help to couple the primary and secondary together over large distances)
and the massive peak energy levels which result in large streamers
becoming visible. - this can result in peak powers of several MEGAWATTS
now the mains is often not capable of providing thousands or even
hundreds of amps - and even more so especially when the voltage is
stepped up through a transformer this becomes practically impossible
unless you own a power station.
Hence this is one reason we use capacitors.....
the reason we don't use 50 hz is because of physical size restraints and
budgets.
but basically IT WOULDN'T MATTER WHAT FREQUENCY THE MAINS WAS - we would
NEVER PLUG A TESLA COIL DIRECTLY INTO THE MAINS - because we would lose
the defining features of a Tesla coil. Even if we tuned it to 50 hz, it
would only resonate at this frequency and would still not function as a
disruptive discharge coil displaying the effects we associate with Tesla
coils.

So I just built my first solid state coil this year, and in thinking about
the nature of primary circuit driving, I got wondering, wouldn't it be
possible to design a Tesla Coil in which the secondary resonated at (or
near) 60/50Hz? The primary coil could be plugged directed into the wall with
no need for any driving circuitry, save for maybe a reactor to limit the
current.
Thoughts? Has anyone tried this?
Cheers!
