I'm not sure if, sonically, that's a good idea. Best speak to Shuggie (Hugo) about that, as I believe he's fitted one to his SA-750.

I am having a custom arm mounting collar made for the Jelco, to resolve the vertical rocking problem. The main difference over the stock collar is a bit of extra height, so that the grub screw presses on the arm pillar in a better place (eg not at the very top of the collar); also the grub screw itself is much bigger so it should be possible to just 'nip' the thing tight without boring into the soft metal of the arm pillar.
