No...not a good idea. The thing you are trying to do is to create a non-pol lytic.
This is possible ONLY if you pull the centepoint to a potential that is ALWAYS above (if it is the two plusses) the voltage you are passing through. But, if you have a transformer the two voltages are not referenced to each other, and if it is an ACDC set, then such potential may or may not be present in the schematic.
See if it is even remotely possible to cram the cap inside without touching something hot.
Or if you are willing to sacrifice some aesthetics and dissing by purists, if you could put a film cap in a box and attach it to the cord somehow to make the third wire for filaments; a 3-wire cord could be used.
