Yes. That will work to help keep it in place.
You can also layer the Pine Bark Nuggets with Shredded Pine Bark Mulch, if it is available. I have slight flooding problems during heavy rains, and I have always used that mix. It has worked well.
But, recently the garden centers were out of Shredded Pine Bark Mulch, and I had to substitute Shredded Cedar with the Pine Bark Nuggets in one area. It flooded the next day, and it didn't move, at all.
The only disadvantage is the cedar not breaking down as fast, and providing as much nutrients (as you probably already know). It also might discourage beneficial bugs, to some extent, which is not something I wish to do.
(Edited) I probably should have mentioned that in hurricane season, we have to move our cars to higher ground, so buoyancy of the mulch is a major issue.
Even though I suggested an answer to your question, I am curious about what works best for you and everyone else, too.
Here are some links:
And here is one that came up from this very site! What are the pros/cons of different mulches?
