        I'm sure there will be several replies to this, but no, it would not be
feasible-- since the flash tubes are evacuated.  As you would know if you
studied plasma spheres and flourescent bulbs, low pressure environments conduct
more readily than higher pressure ones.  As a result, a low-pressure gap would
simply arc instead of disruptively discharging, since the cap wouldn't have
time to build up a charge before the gap started to conduct.  
        If you went in the other direction, and managed to create a feasibly
contained high pressure gap, using air, hydrogen or some other insulating
it would be a different story altogether.  However, since this creates certain
design problems for the hobbyist, the high pressure gap is almost never used in
Tesla coil work. 
        Hope I could be of some help.
