OK, so someone gave me a great idea for a switch in the game playing! I have a party of 5 10th level characters. They are going to be transported to a new time and they are going to assume 5 new "bodies" from the past. But I need writeups including random new equipment. Is there anyone willing to help me generate these characters???

All 10th level
Bladesinger (Elf)
Battlemaster (human)
Totem warrior barbarian (dwarven)
Paladin (Dragonborn)
War priest (dwarven)

What I'm hoping for is the same general classes, but not the same specialization so they have to adapt to the new abilities, spells etc. If they could be a different race then the existing one, that would be optimum. I would really appreciate any help and any suggestions would be awesome
