Probably. But if you really still want to do that, make sure it's OK with your school. I know my med school wouldn't let you do more than 2 rotations in the same specialty.
I did a total of 10 1/2 weeks of Neuro in med school. It was 2 weeks in a Psych/Neuro rotation, a month at my school as an M4, and a 4 week away rotation at where I ended up matching. That was fine. I think 2 in the same place may be a bit much.
There are alot of really good neuroelectives as well such as pediatric neurology, neurology research, that delves more deeply than a general neurology rotation does.
