Can you swap one for the other?
Only partly. Most of barley's flavor molecules (253 of 353) are also found in pepper, but pepper has 207 that barley lacks. Barley gives you part of pepper's character without most of its herbal side. This compares flavor only; texture, moisture and the job each does in a dish matter too.
