I haven't either, although recently I've resorted to having him suicide using traps and setting fire to spider walkways to trigger the required death scene earlier in the game. It has also occurred to me that my characters would rather romance Halsin, anyway. A relationship that requires the level of micromanagement that Gale's does hardly seems worth the trouble and certainly loses its "romantic" feel.
Although, the micromanagement may only be necessary if you want him as a party date. It's possible that a more leisurely romance could blossom later in the game if you have sufficient rep with him (which I would actually prefer). Regardless, if he wants to court my characters, he's going to have to be a little more forthcoming and flexible.
