If he wants everything he touches to burst into flames, sure.
But probably not, no. It worked for Kuzan's leg, but I can't see it work out for Sabo's arm.
How about Sabo takes his arm with him, later meets Luffy and Law and the latter uses the Ope Ope no Mi to reattach Sabo's arm?
Is the "Sabo is losing a limb" thing confirmed btw? I though it was just Lebrent trolling earlier
