You can't embed USE conditionals inside ESVN_REPO_URI, since USE
conditionals like those are only supported in specific variables:
*DEPEND, RESTRICT, SRC_URI, PROPERTIES, and PROVIDE.

A brief examination of the subversion_fetch() function inside
/usr/portage/eclass/subversion.eclass suggests that ESVN_REPO_URI is
expected to be single-valued. So, I suspect that you will want to
define your own src_unpack() function (overriding
subversion_src_unpack) which will call subversion_fetch() as many
times as necessary. See the attached code for example.

["src_unpack" (text/plain)]

src_unpack() {
	subversion_fetch https://kicad.svn.sourceforge.net/svnroot/kicad/trunk/kicad
	use minimal || subversion_fetch https://kicad.svn.sourceforge.net/svnroot/kicad/trunk/kicad-library
	use doc && subversion_fetch https://kicad.svn.sourceforge.net/svnroot/kicad/trunk/kicad-doc
}
