I think what you plan on doing will work great because you fly/lure will suspend in shallow water since the components do not include a lead cone or lead jighead. I've been planning on using curly tail grubs for black rockfish and ling cod along the shallows near a jetty using a 8wt or 10 weight rod. Some of the areas are really snaggy, so a fly rod delivery with the appropriate sink rate line will keep fly/lure in the target zone longer. A purist won't consider this fly fishing but I'm not overly concerned with that. Besides, I've been wondering what to do with the several hundred curly tail grubs and plastic skirts that I've acquired over the years. Have fun.
