Captain, since Experience progression is linked to Steam account, you can delete the current character on PVP 1 and create a new one, with another name. In case you have some assets (gold, ships, upgrades) on the character you want to delete, you can trade it to a friend to get it back with a new character
Feel free to delete, characters on other servers won't be affected, but take care of labor hours reset upon creation of new character, use them on any character on PVE or PVP 2, since when you create a character, labor hours starts from 0
