I play GTA very actively on the Playstation 4, but I noticed very late that I'm on a wrong PSN account games. Is it somehow possible that I transfer my GTA V Online character with all drum and drann to another PSN account and then play with it as usual GTA V Online? I would not care about trophies.
No. Or, as I just read it again:

Question: I just found out that I linked the wrong Xbox Live Gamertag / PlayStation Network ID to my Rockstar Games Social Club account. Can I change it?
Answer: Yes. Xbox Live and PlayStation Network, you can only have one account at any time, so you can change it at any time.
