Solved the problem by using a custom stash (example attached) and
overriding the get method.  As a side note, also needed to override the
private _assign method due to a line in Template::Stash that read

    if ($rootref eq 'HASH' || $rootref eq __PACKAGE__) {

which i needed to translate to

    if ($rootref eq 'HASH' || UNIVERSAL::isa($root, __PACKAGE__)) {

to inherit the Template::Stash object.
Cheers
