Honestly this is an invitation to break the economy. I don't see BW implementing this, mainly because it's simply not smart to do it. If they started selling credits, everything goes up in price, and you end up having to grind the crap out of dailies and TFB to be able to afford anything.
If you are in that much of a credit crisis, take the mentioned $60 and spend some money on coins. Then, wait till the next cartel pack drops and just buy as many of them as you can, you'll make upwards of 4 million credits. I did that on the last pack's drop, and I was about 2 weeks after it; still made almost 5 mil credits.
