If you wait 3 weeks between regurge and feeding again you'll probably be fine upsizing after the first meal she keeps down. To me, the difference of a few grams is minor when looking big picture, so I'd probably go with a hopper again for the second meal, but I tend to feed on the conservative side.
Others may have different advice, but that's what I would do. She'll start putting on some healthy weight once she's on more substantial prey. But it can't hurt to hear some other replies and trust your gut.
Good luck! Please keep us posted.
