Well if you wanted to get someone ranked up you could rank them up with Destiny by Enstone. You can google that to find out more. But you cannot unlock all for anyone, it only ranks them up to master prestige thats it.
And im pretty sure menus like Project TCM may have an xp option, not sure if they work or not because ive never used it but you can give it a shot. Use a GSC injector for TCM.
