From all you've said, I'm certainly hoping to find it. My Fighter/Mage/Thief currently gets three attacks with the Long Bow of Marksmanship and two with her Two-Handed Sword +4: Backbiter.
I've found that soloing a Fighter/Mage/Thief is quite fun and the combination of classes works well. An Improved Invisible, Stoneskinned, Mirror Imaged, Hasted Fighter is quite deadly.
