But you will not be able to meet the goal of being able to switch old working copies from the old monolithic repository to either of the new repositories. A working copy is tied to a repository by UUID. A UUID uniquely identifies a repository. Your plan is to retire the old repository and create two new repositories, each of which contains a portion of the old repository. Both new repositories will have new UUIDs and users will need to check out new working copies from either of them, and discard their existing working copies of the old repo.

For users of the projects that remain in the repo, possibly yes. For users who had working copies of the old now-removed projects, they will receive confusing error messages if they try to use those old working copies.
The purpose of the UUID is to uniquely identify a repository. If you go do surgery to your repository to change its contents (e.g. using svnadmin dump / svndumpfilter / svnadmin load), IMHO that makes it no longer the same repository, so giving it a new UUID makes sense. But it does come with the inconveniences mentioned above.
