Anyway, I suppose you have a point that a situatuion where Sakazuki would view Luffy as a boon is more likely to occur, whether through a position as a shichibukai or whatever I don't quite know, while in any interaction with Teach, BB would always be looking for a way to turn it to his own personal advantage, which wold make the crew at least trust him less. Still, even if it doesn't quite answer your initial question, I think Luffy is and will continue to be far more angry at Sakazuki... so any interaction with him would require an intermediary, like Fujitora perhaps, Luffy seems to have decided he's alright...
