Sketches - Logo Modifier

Adding a modifier on to an existing product logo. Looking to make something that works with the existing typographic logo. My inspiration is coming from over the counter drugstore labeling. This is along the lines of "Tylenol", "Tylenol Extra Strength", "Tylenol PM" etc.

The challenge here is making something that is noticeable and differentiates the product without clashing with an already detailed logo.
