Theory does not work at all firstly it was discusses earlier that a person with a devil fruit cannot consume another because the devils in the fruits will fight amonst each other for dominance ultimately destroying the host.

Secondly when someone which a devil fruit dies the power is transfered into the closest fruit within proximity to person deceased. Regular fruits can become devil fruits. Theres a picture of this happening.

Lastly I personally feel it had something to do with Coa + friction and heat caused by gear 2.
