Simple answer: Depends on you.
This is a very subjective questions. As nobody knows the circumstances you're in.
- If you think you need both in the near future -> Sure
- You just want to add 2 new languages to your resumé? -> Sure
- You are capable of learning 2 new programming languages at the same time -> Sure
However, you'll probably not have such a deep understanding of the language as if you'd learn them one by one, digging into the special features offered by each respective languange.
