There have been some good tips here, and as someone posted earlier from a pure mathematical approach this should be possible. However, the math doesn't always work in practice. I had a similar goal a few years back where I dieted from the 20% range to about the 10% range and really wanted to get down to 6-8% so I upped the intensity, but I crashed and burned HARD.
I really don't want to discourage you, because your progress is awesome, and your motivation is definitely there. But I would agree with Jakabol in the fact that after having been through a pretty significant cut already you may need a more moderate approach to getting the last bit of fat off or you may end up hitting a wall.
If you have the motivation, I think it can be done, but it will require absolute determination and no screw ups. A small mistake can set the train on the wrong track.
One tip from past experience: you look great already according to the pics, so you may not want to be too aggressive, you can definitely slow down and take a more moderate approach and take your time with it. Be happy with the progress you have made, and just make sure that you are constantly making more progress, but it doesn't have to be an all or nothing deal. Be in it for the long run!
Now that that's out of the way, I am definitely going to follow this thread, if you go for it make sure to keep us updated. Good luck buddy!
With regards to the training, I think everyone else's advice here has been solid. Big compound movements and HIIT will get you there. But I don't know if you need HIIT more than 3 times a week, you may burn yourself out especially on a low carb diet.
