Imagine if Oda was saving the T-Rex fruit for Franky somehow? Maybe even feeding it to one of his Franky creations? Mecha Godzilla, Franky style even? Well would need a Godzilla/Kaiju fruit for that I imagine but still?
If Franky does eat a dinosaur fruit, it would totally have vibes of this then, especially with Sanji too ofc and him getting Queen's tech as he desires too ideally!:
