Only if you're cool with Randy, the Magic-Loving Demon Belt
Helm of Opposite Alignment:
When placed upon the head, this item's curse immediately takes effect (Will DC 15 negates). On a failed save, the alignment of the wearer is radically altered to an alignment as different as possible from the former alignment—good to evil, chaotic to lawful, neutral to some extreme commitment (LE, LG, CE, or CG). Alteration in alignment is mental as well as moral, and the individual changed by the magic thoroughly enjoys his new outlook. A character who succeeds on his save can continue to wear the helmet without suffering the effect of the curse, but if he takes it off and later puts it on again, another save is required.
Only a wish or a miracle can restore a character's former alignment, and the affected individual does not make any attempt to return to the former alignment. In fact, he views the prospect with horror and avoids it in any way possible. If a character of a class with an alignment requirement is affected, an atonement spell is needed as well if the curse is to be obliterated. When a helm of opposite alignment has functioned once, it loses its magical properties.
Put the helmet on the belt, which changes its alignment, as per the above quoted text.
Of course, some GMs will rule that this is 'mind-affecting' (though, RAW, it's not), so for full effect it should be preceded by Polymorph Any Object to give the belt a type more amiable to subjugation. In any case, you'll need to give it a head, but that can be done much cheaper (such as via alter self). Being LG, the belt's alignment will permanently change to CE, and the polymorph effects can then be safely dismissed.
I make no guarantees that your new belt-friend will be less likely to hurl you off into nearby lava pits.
Note: Polymorph Any Object does not work on magical objects in general, but it does work on intelligent items; they also count as constructs and the spell can target constructs
