Your desired output looks more like an AoH. It doesn't have any keys in the top level.

Yet another combinatorial problem. Let's try glob again, 

sub hoa2aoh {
    my $hoa = shift;
    my @keys = keys %$hoa;
    my @patterns = map {
        local $" = ',';
        "{@$_}";
    } values %$hoa;
    [
        map {
            my %hash;
            @hash{@keys} = split ','; # char changed from "\0"
            \%hash;
        } glob join ',', @patterns
    ];
}

As I say, that returns a reference to an array of hashes.

Update: glob wasn't liking the "\0" seperator I used at first. It didn't like whitespace, either. Changed to comma, it works now. Also removed superfluous variable.
