Depends on what team he went. Being the usual dominant player, if he went to a team of the equivalent caliber of the Miami Heat in the West, i.e a big market that goes championship or bust so much, with a good coaching legacy, I don't see why he couldn't make it 7 times. He always attracted stars, since Miami, he usually always had great role players, If he did go to somewhere like GSW or the Clippers, he would've had even more money to play with and a less greedy front office as CLE had in LeBron' first stint.
If someone like Kobe can make 7, I don't see why arguably the most versatile player ever couldn't do it
