how to have working copy be subset of large tree?

I'm not sure how to do this cleanly...

I'm playing with some Python projects that already exist, so they're already
installed in the Python root directory (E:\Python23 in my case)

I want to have some of the directories under E:\Python23 as my working copy of
the project, but other directories are not. But it's not just a branch of the
dir tree; it's several branches with no common top directory:

This also opens up a secondary question - if I do this how I *think* I should do
this, what if I'm working on multiple separate projects that have the same root
directory? I'll explain that question in a moment.

The project currently lives as installed in the Python root dir:

        (other dirs I DON'T want as part of wc)
                        (other dirs I DON'T want as part of wc)
                (other dirs I DON'T want as part of wc)

From above, I want as my working copy to contain:

I've created a tree in the repository with the directories and files I want; the
subset from Python23\*
repositoryRoot\projectFoo\trunk is at the same level as Python23, so I have:
repositoryRoot\projectFoo\trunk \scripts

But how do I create a working copy - I can't do a checkout into the
already-existing E:\Python23 because the directories and files already exist.

I've thought of two methods:

(1) Delete the files and dirs that are in the repository and then just check
them out as
        svn co repositoryRoot\projectFoo\trunk E:\Python23

(2) rename E:\Python23 to something else
create a new empty E:\Python23 and checkout the projectFoo\trunk to it
copy everything from the former E:\Python23 into the new E:\Python23
(this would overwrite the checked-out files with duplicate copies but that's ok,
isn't it? timestamps would change though)

Is there a cleaner way to checkout the project I want, overlaying it on top of
already-created files of the same name?

Now, to the question I mentioned above - if I do either of the above, I'll end
up with projectFoo's top directory being E:\Python23 - i.e., I can do updates
and commits from that directory and I'll get all the working copy at once, just
as I do with other projects.
(I'll have to svn:ignore the branches I don't want to version)

But what if I'm also working on other projects in the Python23 tree?

Say, projectBar which has similar projectBar directories under lib and share?

If I do the same thing with them, I'll end up with E:\Python23 trying to be the
top directory of *both* working copies - which won't work at all, I'm sure.

So is this even possible to do?

Any ideas of a clean way to do this?

(hoping I'm not opening a can of worms like my other question... :)
