Well... I don't know. Anyone who wanted to go through the steps of adding a couple other flavors like I did could get near to Dr. Pepper perfection... but a lot of folks don't want to bother. If your factory can get it there, that'd probably be the way to go. Or as close to it as possible...
Until then, I'm now happy

As a bright side, adding the other flavors appears to have increased my throat hit

If I run out of my sample before you get a new factory sample, I'll probably be ordering some to play with again. And at the rate I'm going, I'll probably run out tonight
