Model change on rick click *without replacing block* Help needed!

Hey there, I'm currently trying to make a mod with animated block models, I am using the workaround where you put all the animation frames into one model with an animated texture so it only shows one frame at a time,

think of a furnace when it has items burning inside it uses the lit texture but doesn't replace the block it's self since it keeps all the items inside, I want that, I would like to have my block use a static model but when a player right-clicks my block it will change models as long as the required item is inside its gui..

Please do remember I want my block to have a GUI so I will not be replacing the block with a duplicate that has the animated model, I am looking for a way to keep the items..

Thank you in advance for any help!
