If you add 60 g at 3/9, that will increase SW about 90 g - that's a lot.
It will also be enormously HH unless you counter with roughly 60G in the handle area. If you counter weight the handle, you will have added about 4 oz to the racket. If you leave it that HH, I expect it would take some time getting used to and god knows what it will do to your swing mechanics.
Dr Frank-en-stein has gone mad.
How about adding a little weight at 3 and 9 to increase twist weight and work hard to hit it near the center with a slightly closed racket face at impact.
Don't worry dear friend, I have all those bases covered. Just need to find the right platform frame. In general, some people don't seem to have the spirit for experimentation. That's OK too.
