No that will most likely not work. Ever profile has a unique hash via hex editor. It is possible to change it up to anther profile but you need some very good skills in hex to do so. I'm not just talking to talk about this, i'm serous and it CAN be done. My friend no longer messes with this kind of stuff anymore and I am no good in hex.
Step one. Lay on floor Step two. Try not to cry Step three. I think you know where I'm going with this
Just don't mod your gamerscore at all or just don't mod it out of hand like you obviously did considering you had 200k.
Like they said, learn from your mistake. There is no easy way around this and you won't be able to use the same gamertag. IF... you still want to mod your achievements, be careful. Microsoft sees the time stamps on them. and they know you can't get 10,000 GS in one day. They also know what achievements take longer. They are slightly lenient on out of order chevo's as sometimes it happens. But they also know this is RARE. I personally will NOT use profile editor. The safest bet (other than legit) is to DL achievement popper saves and do them offline.
