Generally speaking, salmon has more restrictions than other fishing, so any method acceptable for salmon should be acceptable for other fish. Methods are more relaxed south of Pt Conception anyway.
Your risk (and it's a big one) is NOT catching a salmon in sight of DFG using lures that are designed for salmon. If you don't have any fish on board, then it's your word against theirs that you are "targeting" salmon or seabass.
You'll pretty much be 100% guilty if you hook and reel in a salmon on your "WSB flasher rig". You'll be 100% innocent if you reel in a WSB. With no fish on board, you may be 50/50. However, being south of Pt Conception, you may be 75/25 innocent in their eyes. On the other hand, if some salmon has been caught near the area, you may just become 90% guilty even with no fish on board. The closer we get to April probably also shifts the presumption of innocence closer to presumption of guilt.
It seems like some grey area to me. If you're comfortable with grey areas, go for it. If not, keep the salmon gear at home.
So you just have to ask yourself one question, "Do you feel lucky?"
