And another idea: add the twists in stages, inner twists first, just letting the spokes cross where the outer twists should be. Then add the outer twists one side at a time.
The long nipple trick above sounded good too, but you need to use nipples that actually have longer thread. I think DT swiss gain 1mm of thread for every 2mm of extra length, but as i understand it sapim nipples don't.
Another crazy idea: initially build each flange to a separate rim. Twisting one rim against the other should give loads of leverage for stretching the spokes.
