It's a pretty name, I would never have thought of the "I feel ya" or necrophilia comparisons, and I dont think people will either. I think youre overthinking it when it comes to syllables, because it sounds fine with
Scarlett and
Malcom.
As long as names have a nice flow and dont seem to come out of left field I doubt people are going to be so thrown off that they cant pronounce it, etc... Its a good choice for a pretty, interesting, unique name that seems to come naturally and isnt trying too hard, pair it with a simple or common middle name and I think you will have a real classy winner.
BTW
Josephine is my fav
