Do you really need to do this? You would not be using strict and you would be using symbolic references if you actually do this. Can't you just create a master hash of hashes, and have the keys be the value your talking about?
my %master;
$master{$hashref->{y}}{$hashref->{z}} = 'value';

# In the spirit of giving 'em enough rope,
# and hoping I never have to maintain the code,
# here's the symbolic reference version
${$$hashref{y}}->{$$hashref{z}} = 'value';
