This has been done. In fact, I have flashed an AT&T 920, 820, and 640 already to CV firmware although they require extra steps. If you follow along with Windows Central you should be aware of this by now. But yes, it is an additional challenge with AT&T phones. My local Metro PCS was still selling 640s the last time I was they (maybe 2 weeks ago) and those are super easy to flash.
i do follow windows central, and since the flood of AT&T 640's after bestbuy's $29 BF and microsoft store selling at $39. there have been countless posts on here and all over the web of people wanting to turn it into a tmobile version. all ive seen/heard is that its not possible yet.
edit to add: im talking specifically about the AT&T version. i know other version can load different software
