That's what I do exactly, but I use a 5 gallon bucket so that I can leave the roller in it, with the lid snapped on. I hang the bucket by it's bail on a "hook bent" nail driven into the back of the plate's supports. I haven't been adding the white lithium grease, but might try it. The latex paint mixed with new oil has been entirely satisfactory for me.
When testing loads or guns, and want to save the patterns, I place a card with a number on top of the plate and snap a pic with my cell phone. Then I can email them to myself, move to my pics on my computer, and on to Photobucket if desired.
