Self inductance of caps/ self capacitance of coils is a technique 
sometimes used in radio freq. design... It can be done, but you would 
need to carefully work it out. I doubt if a shop bought cap would 
fortuitously work like this for a coil. Maybe consider the reverse: 
aprimary coil wound of a flat ribbon wire such that there was a high 
cap. between windings?
