You can certainly do that! If it were me, I would leave the class title the same as the college title, and not weight the grade.
Many sources opine that, "One college class generally equals one high school credit" (even HSLDA). However, it is incumbent on us homeschoolers to investigate what the legal rules in our particular state actually are. For example, in Florida the DOE has a document that correlates the college class code with the equivalent high school credit. Sometimes the college class is worth 1 credit (e.g., science with lab), but sometimes it is only worth 1/2 credit (science without lab). It would be questionable (at least in my mind) to award more credit for a college course than the DOE has authorized. Here is the link for Florida; I'm assuming other states may have similar regulation:

Dear Jennifer -
You are absolutely right. It is ALWAYS prudent to check with your state's requirements. Thank you for the link!
