600cc pec implants or more possible? (photos)

Hello docs, so I plan to have pec implants to increase my already large chest. I’m 6ft 240lbs of mostly muscle. The problem is I want to go very dramatic. I’d like my pecs to be disproportionately large on purpose and I’ve yet to see any results that have given that. Is it possible to customize a size in the 600-800cc range? I’ve attached a pic of me. Thanks
