Sorry, yes. Lucky Rabbit Foot cannot be used to make a Super Lucky Rabbit Foot Belt. Item does exist in game, but I do not know if it drops. I'm going to ask that it be added to the missing recipes mod.
Regular Rabbit Foot can be used to make a Super Rabbit Foot Belt: LOOT_Paw_A_Rabbit_A + TOOL_Pouch_Dust_Pixie_A = LOOT_Paw_A_Rabbit_A_Magic + LOOT_Thread_A = LOOT_Rabbit_Paw_MagicAmulet_A + LOOT_String_Bow_A = LOOT_Rabbit_Paw_SuperAmulet_A + LOOT_Rope_A = LOOT_Rabbit_Paw_SuperBelt_A
