Hmm. There was a guy on OGR who was messing with a DIY circuit, hooked the capacitor (IIRC of similar value to what you're proposing) backwards, it exploded and started a fire. He happened to have a fire extinguisher and took care of it.
Increasing the capacitor increases the amount of stored energy and the amount of power flowing into the lower resistance coil. I suppose electricity is still "cheap" in the US and we aren't talking megawatts. But as a rule-of-thumb I try to reduce power consumption in circuits which generally improves reliability, allows use of smaller and less expensive components, reduces heat-management issues such as needing ventilation, etc..
It's a tradeoff with how much "math" you want to deal with, waiting weeks for stuff from eBay Asia, using Radio Shack as your supplier-of-choice because it's down the street, soldering seemingly microscopic components, dealing with geeky schematic diagrams, and so on. Whatever works for you...
