Considering the magic powers that Stands exhibit probably the answer is no, but who knows man you just need an arrow

Nah, it wasn't the arrow, it was a meteor virus lol

Natural stands are either developed when born, linked to your lineage, or developed through enough work and practice into the occult; for example(s): Kakyoin's is in-born as he had it since he was a child. Avdol's was developed through his practice in the occult. Jotaro, Joseph, Josuke, and Holly's are lineage based, though they're arguably also linked to the arrow, since they developed after Dio, attached to Jonathan's body, was pierced. 
Arrow stands seem to develop what one requires the most, though it's hard to say if that remains the same post-part4 as they seem to start getting more and more random. Killer Queen, for example, is perfect for Kira, as it allows him to discreetly destroy evidence of his murders. It's also heavily implied his father used to help him get rid of the bodies before, and his stand allows him to trap people in a photographed room which would help against non-stand user investigators.
GE Requiem is kind of not an actual stand, since it only came to be after GE was pierced by the arrow. It's more like an evolution of a stand, giving it lucidity/self-consciousness, unless it shares Giorno's consciousnesses. Requiem stands are broken as shit and almost impossible to understand why they turn out the way they do though, fucking silver chariot's requiem ability switched people's souls based on proximity, unless requiem stands get specifically something that would help at that exact moment. 


The arrows were made from the meteor. Contact with the meteor would bestow people power if they had a strong enough will, otherwise it'd just kill you horribly. The arrow works the same way, except it can sense those with a strong will and has an almost magnetic attraction to them.
Koichi was in the process of dying from the arrow, but being healed by Josuke meant he survived and his stand developed much slower, which is why he laid an egg.


Different universe. Or rather, that was only after the universe was reset.
