I would not, thanks for asking.

As for whether this could be accomplished, I think the current cultured meat trials are relatively small quantities, and you get into structural issues beyond a certain size. Maybe blue whales have muscles that are the size of a lounge chair, like their tongues? I'm not sure about cetacean anatomy. But by and large you're not going to get a single muscle body that's anywhere near that size so then your stringing things together and are we trying to buy engineer that or are we just using a shitload of transglutaminase? And then you're going to want to seal it so it doesn't rot, as somebody else suggested, and at that point you're not even getting the texture of the meat so what's the point? Unless you wanted it to just be a living custom genetically engineered organism that's mostly tongue just for your sitting pleasure which seems like a bit of a horror movie premise if I'm honest lol
