Golf: adding lead tape to a driver

I am currently hitting the Ping G30 with an Aldila RIP stiff flex tipped .5" so it plays a little stiffer. I don't want to go X flex because I don't want to spend money (have you seen the price of oil lately) and I don't want to swing that hard because I will blow out my back. I have been fighting a slice lately which is killing my scores because I'm hitting everything but driver really well. I was reading about the Ping G30 SF tec (straight flight technology) and they added more weight toward the heel allowing the toe to come through faster helping someone who slices the ball. In theory adding some lead tape toward the heel would accomplish the same thing right? I'm afraid I would start duck hooking everything. What would be some negatives of doing this other than having to get used to the heavier club?

I know the problem is in my swing. I'm pulling my hands through at impact instead of letting my wrists come through like they are supposed to. With my job and wife and three kids I don't have time to practice and I only play once a week. I don't want to skip the money game to practice so I'm looking for a short term fix until I can fix my swing

Eta: that's really long. I probably wouldn't read it either.
