The Hebraic letters are somewhat stylized, and the exact shape of the goat is unique. Given that the goat is the most artistically significant part of the Baphomet, if you must determine whether a Baphomet is the Hell's Kitchen Baphomet (the name given to the official CoS variant) I would compare the goat from a known "official" version directly.
Also note that as far as I'm aware, merely adding something or subtraction something will not guard against copyright violation; removing the Hebraic letters and adding something else yet leaving the design of the goat unaltered is still copyright violation unless you had permission for use.
"The devil I'll bring you," answered Hagen. "I have enough to carry with my shield and breastplate; my helm is bright, the sword is in my hand, therefore I bring you naught."
