I think that pretending your history were all touching paths with client_repo/brah2/ prefixed to them so that the shape of the working tree resembles with each other is the easiest part of the problem. You could filter-branch or filter-repo your history or even create a fast-export stream and munge paths in it before running fast-import on the result. A much bigger issue is what you want to record as the result of such a merge. Your client repository may have their own changes they want to keep, and your repository (with paths appropriately munged to match) would also have your changes you want to keep. Obviously there won't be any common ancestor between these two histories, as they evolved independently without being aware of the other. "git merge --allow-unrelated-histories" would give you a chance to record the result of such a merge, but you'd need to sort the conflict out to match your customer needs.
