My understanding (you'd probably want to just try it) is that Yes you
can do this. This is really just client-side URL transformation so I
do not think it matters that it would cross a repository root, and I
recall your example as being desired functionality.

In the release notes:

http://subversion.tigris.org/svn_1.5_releasenotes.html#externals

Your second question is even given as an example.

The opposite (although I might be reading you wrong). The idea here
is that people with write access are using https:// and people with
read access are using http://. With full URL's you cannot handle this
really well. This allows the scheme to change based on the scheme
used for checkout.

Reading the release notes, I now see that the text for this one and
the previous is wrong. What this one adds to the above, is that it
allows the scheme and hostname to vary. Picture someone on internal
network that uses svn://internal-host and someone on outside that uses
https://external-host.
