Don't you think that power up would kinda suck? as someone who bashes Sanji a lot, i think this would be even worse than the Raid Suit.
I don't know, Luffy is already the fucking Chosen One getting power ups up his ass a lot, but even him had to train this arc.
Zoro also had to train with Enma, and even Zoro could still have some bullshit of being related to Ryuma / Shimotsuki, or maybe not. But his powers still seem to come from training, but he did get CoC this arc (actually he had it since Enies Lobby, he is just learning about it now).
But Sanji's first power up was the Raid Suit that he could've put on back during the East Blue if he had it then and still kick a lot of fucking ass without training, in fact he could probably take out both Luffy and Zoro back in the East Blue just with the Raid Suit and no training for it. Now he might get another power up related to DNA stuff that they did on him before he was even born and get more powerful out of nowhere? wouldn't that fucking suck? at least i think so.
An honest opinion of someone who isn't a Sanji fan.
