Wow this is something I had floated by me by another member on using capacitors. Sounded very interesting to me.
Seems you are doing it.

Please cut us in on some picture and as much info as you care to. Very interested in this
mod of yours for some ideas on the idea floated by me a while back.
Seems by doing a search on using capacitors all I came up with was some stuff on how if they shorted the result wasn`t pretty. So why short them I thought. They should be able to be made safely to not short.
Very interested in this and your thoughts here.
