Could Fujitora crush everyone?

[Warmmedown]

If he can control gravity, can he not just crush Shanks? Make his head 1,000,000,000,000kg, instantly breaking his bones. Seriously though, could he not do something like that? When Law was running away from him, he could have made Law really heavy, so can't move. Or tortured him, by making him slightly heavier. Law would wonder why he's getting so tired in his monologue, and then be like "No! It can't be!" with wide eyes, then turns and says "Fujitora, omai..." and Fujitora says "so you've realised. I'm both disappointed it took you so long and impressed by your stamina. Yes, I've made you heavier, just enough to make you think you had a chance of escape, just enough to enjoy the pleasure of hearing your vigour drain from your youthful body. Also, I am your father" then he crushes him instantly.

Couldn't he make Zoro really light or just reverse gravity so he flies into the sky? Zoro will be like "where the fuck am I, I'm lost again", then realises he's on the moon and can't breathe.

Haki can probably resist it. Law is able to overpower Doc Q's devil fruit after Wano using Haki.
