For a 10" pin, you could mark a anti-pin on the opposite side of the ball and drill it like a 3-4" pin ball using the anti-pin.  Kinda like Visionary's AMB system.  A 7" pin would still give you a 6-7" anti-pin length, so it may not help much.

What I'd be worried about is how much bottom weight you'd start with using the anti-pin.  Whatever the top weight was to start with, that's how much bottom weight you'd start with using the anti-pin.  A 10"-pin, though, might very well have almost no top weight, if only to get so much weight on the bottom of the ball to create such a long pin.

It's not ideal, but what else are you gonna do with a 10" pin?
