Sounds doable. Two weeks of preparation left you pretty much still a newbie. So by taking things to the next level you could push up your score as much as you are looking to.
Have to play a tight game though.
Every move has to have decent ROI. For instance, it might bug you that you can't do much with a certain specific quant problem type, such as permutations, but working a lot on that topic does not have great ROI. Probably you would gain more from working on things that can be applied more generally, such as algebra.
It looks as if you are pretty skilled in verbal already. What that might mean is that with a little more knowledge of how the questions work you could get significantly more right. For one thing, Critical Reasoning and Reading Comprehension are so logic based that you barely need to learn anything new to rock them. You just need to get more skilled at reading carefully and seeing the logic of what is going on. Also, if you learn a handful of key things like the fact that on an inference question the inference has to be true based on the information in the prompt, then you will do the questions more quickly and answer more accurately.
Beyond that, by getting a little more clear regarding things like placement of modifiers, subject verb agreement and parallelism of lists, you could improve your accuracy in Sentence Correction.
On quant, as Rich said, likely there is plenty of low hanging fruit. For instance, if you just get a little better at handling certain things such as Data Sufficiency, triangles and absolute value, things that will definitely or likely show up on the test, you will gain points quickly, both from getting those questions right and from speeding up your calculations so that you have more time for other questions.
Another cool thing to consider is that logic similar to what you are using to get verbal questions right can be applied to getting quant questions right. You may just need to get skilled in using the mathematical building blocks of the quant questions.
So yes, if you really spend the amount of time you said you have to spend, and invest it wisely, you can really develop some skill in playing this game called the GMAT. So achieving that goal, especially the 700, is totally possible. Push the verbal up to 44, which is not very far, and the quant up to 44, which is reasonable, and there's 710 - 720, and who knows, maybe you will score even higher.
Be sure to use official GMAT practice CATs from GMAT Prep along the way.
