Even if Jotaro inheritted something from Jonathan, It shoudnt be realy possible for them to have nearly exactly the same stand. There is a precident for this, with Tomb of the Boom being inherited by each family member. Though I suppose that does beg the question why we don't have Purple Hermit: The World. Tl;dr: Hermit Purple is linked to Hamon, which Jotaro and Josuke don't have and so they can have punching ghosts rather than vines.

I'm pretty sure we have close to outright confirmation that Hermit Purple is linked to Hamon. Araki once said that if the Pillarmen could have seen Stands, they would have seen something like vines around Joseph. Holly was the child of a (strong) Hamon user and a mother regularly exposed to it. She inherited the aptitude, but never awakened it. When her Stand was then forcibly brought out, it took the form of vines because of that. But we have never seen Jotaro even asking about Hamon. So he likely never knew about it in the first place. Plus Araki wanted to let it fall and express his creativity through Stands. You can only do so much with Hamon.

I'd also argue that Tomb of the Boom being shared is because of the family's awakening at the same time. So it took a form to compliment their cooperation strategies rather than because of their shared blood. They'd still have similar Stands, but with more distinct abilities.

Another interesting point in this argument are Josuke and Crazy Diamond. Direct line to Joseph, but no vines in sight. Probably because of the absence of Hamon. At which point I am back to the beginning of my argument.
