Yes, there are looser interpretations out there.
There are several 'fringe' groups but they are badly persecuted in both Sunni and Shia dominated countries. I suspect just asking about them could get you in serious trouble.
I believe the Druze have a LOT to offer but you would have to be born into it in order to be considered for instruction at the Inner Circle levels. (And they are persecuted even in their own traditional homeland -- the expat Druze community in Los Angeles is now bigger than what remains in Lebanon!)
I think you can do a lot with the Sufi exercises (particularly the silent Dhikr practice).
