One thing that should work, if you find it aesthetically pleasing enough, is a "classic style" threadless stem like the ones Velo Orange carries:
VO Tall-Stack Stem 31.8, 1-1/8" - Threadless Stems - Stems - Components
Similar thought. Threadless stem are designed for compression...the stem squeezing it. A quill stem does the opposite, pushing out from the inside (tension). You will break/crack your steerer tube.
