PC is the only platform that can do it but its weird how you do it, I figured it out due to frustration of the swap glitch that gave me the wrong class. Level carries over however you might have to exit and come back into the game.I cannot 100% confirm this soHere is what you do1. Turn off Steam Cloud Sync, otherwise the cloud will just load your old save back into the files and it'll get confusing. You can turn it on after it's done.2. Back up everything in the remote folder, even the TPP GAME DATA file and put it all somewhere safe.3. When you exit MGO make sure your on the character that you want to change is selected 4.In the Game Options make sure it starts the game with TPP instead of MGO5 Restart the game and get to the TPP Menu6. Go into the TPP Menu and select Delete Save7. Once the game has deleted the save close the game8. Once that is done if you get the EULA Agreement to pop up it means you are on the right track9. Once you are in the menu you hit MGO, if you're seeing the prologue cutscenes after accepting the EULA, you need to back out completely then copy your old save back and replace anything it asks to do then launch the game and go on MGO, like it says.10. Get back to the TPP's menu in the chopper (Where you should be if you copied your save correctly), go on MGO, choose your class11. Then you are able to pick class, WAIT for the class' uniform colour to change before you finalise. Make sure to see the characters uniform changes colors if not then keep playing with menus.12. If you get wrong class repeat until it works properly, once the tutorial is done you should see yourself as level 1 and your desired class.13. Accept your class and go back to TPP just to be safe, then quit the game again, reload it and go back on MGO, this'll get your levels back.If your save doesn't work then try this one http://www.gameforsave.com/blog/metal-gear-solid-5-phantom-pain/ because it worked for meThis will be different weapons, FOB, etc so if you care about FOB'S and Singleplayer stuff then do not use the save!This situation took me about 30 minutes to an hour but in the end I got what I wanted and my character maintained the level from the wrong class and got the gear options from my 2nd Character so i didnt have to grind for that stuff again for Infiltrator.
