If you were using a braid to leader setup, could you use the tag end of an alberto knot and tie the fluke on that? Instead of a swivel?

I use two swivels and a bead:

 

Tie a swivel to the mainline, but put a bead above the swivel and another swivel on top of the bead.

I like the leader extending from the direct tie to be longer than the leader on the top swivel. I fish this

rig weightless with a steady retrieve and an occasional jerk.
