They tend to want 6 months or so between CLI's, so you are right on the edge of that. That said, there are so many factors unique to your individual situation that nobody here can reasonably predict what a lender will decide. If you realistically need the extra spend, then apply for it. If they turn it down, call UW and ask for it to be reconned. If they say no, then they say no, but you'll never know until you ask them.
Off the top of my head, assuming you have the income to support the request, I'd say that your chances are good for some sort of increase. They may counter, but again, until you ask them for one you'll never know.
