Of course.

Imagine this. You have a plaintext file in english and encrypt it with
Blowfish in CBC mode. After you encrypt again this encrypted file with
IDEA in CBC mode.

The increase of security is in originally you have a plaintext and
after the first encryption you have a "random" file so the next
encryption increase segurity because you have encrypted a random file
and not a plaintext file.
