Should not do that if you give it another name. With the same name it
should give you an error though.

Long story short, it's not possible to have different templates for the
same layer, you'll have to publish
the layer twice with two different names, and then add the templates in the
two separate directories.
Thinking about it, it should be possible to write code so that different
templates are used for the
same layer based on some vendor parameter, for example a way could be to
specify a custom
prefix in the request, &format_options=template_prefix:foo and have
GeoServer look for
foo_content.ftl instead of content.ftl. Of course this would need someone
coding such new behavior.
