Can I start now??

It would be impossible to cover the whole syllabus in such less time. Try finishing the topics that cover major part in the exam. Just do them properly and practice questions based on them.
Prepsmarter is pretty amazing. It let you practice topic wise. which is a really unique thing I came across.

Finishing with the syllabus in 30 days with no prior knowledge of finance seems impossible. Anyways, since you have registered for the exam it’s better to give it. Try doing the topics which cover the maximum amount of portion in the exam. You don’t have to do it all , just do 4-5 of them, but do them properly. Take topic based tests and then take 2-3 mocks. This is the only thing you can do right now.
Refer to BT or Schweser notes as study material and Prepsmarter for practicing questions.

Candidates have done it in the past, but it doesn’t mean that this is reliably possible for current candidates. Agree with @JaneDuffy that giving it a good go without putting too much pressure on yourself would be a good experience. At worst it would set yourself up for a good Dec retry – and if you pass that you still wouldn’t miss out on the June 2017 L2 cycle.

Your 11th Hour Guide plan sounds sensible – I’d also keep the full notes handy in case you do get stuck when reviewing/completing practice exams.

Good luck!

Just do what you can. Don’t stress yourself. Either you will clear it or you won’t. i would suggest you to target the next cycle.
All the best!
