The red snapper has some precedent

Although gin may initially appear to be an unconventional choice for a Bloody Mary—especially considering the classic use of vodka—its role in the Red Snapper cocktail is not without merit. Gin is a fundamental spirit that deserves a spot in any bar, and it has a history of serving as a versatile substitute in various cocktails. For instance, the "London Mule" replaces the traditional vodka with a quality London dry gin. Additionally, gin has been featured in classic "hair of the dog" drinks, which is one of the specialties of the Bloody Mary. The pre-prohibition Corpse Reviver No. 2, a revitalizing blend of gin, lemon, Lillet, and orange liqueur, finished with an absinthe rinse, was often enjoyed as a pick-me-up, much like its savory tomato-based counterpart.
It's also important to mention that the Red Snapper we’re discussing isn’t the only cocktail by that name. There exists another distinct drink that mixes whiskey (typically Canadian), amaretto, and cranberry juice, which can be served as either a cocktail or a shot. Therefore, if you order a Red Snapper at a bar, be sure to clarify which version you want—an extra splash of pickle juice would not be pleasant in this particular Red Snapper.
