Probably not. The existing controller's output is not really compatible with another controller's input.

You might be able to bypass the existing controller and take the output from the panel directly, but when combining panels they really should be close-to-identical in voltage and power. Mixing and matching different size panels can be next to impossible.

However, there's no reason that you can't use your existing panel / controller, and then add another panel / panels and another controller for those. Connect both controllers to the battery. There can be minor issues with multiple controllers once the battery approached full-charge, but they will both charge the battery. It will work OK.
