Well, it actually will work like this, with a difference.

Here's what you see if you open the 5uFd and 15 uFd
cans:

The caps are press-fit into the tubs and can't be removed.
I've drilled-out some of the old material and made room 
for new caps.  With the 5 uFd, I notched the
side of the top to allow the negative lead to be soldered
to the can.  The 15 uFd at 25V is much smaller, so 
I offset the hole a bit and tacked-on a longer Negative lead:

My problem with this:  When drilling out the old cap guts,
I can smell and even taste chemicals from inside them 
which become aerosolized during the drilling.
I have no idea what I'm breathing-in during this process,
but I don't like it.  Anyone know if my head is going
to turn green and fall off??
