I am not sure whether this really covers the same topics as what you have in mind, but some people are working quite hard at trying to improve the CPAN and the tools related to it. See for example http://act.qa-hackathon.org/qa2017/, as well as http://blogs.perl.org/users/sawyer_x/2017/05/my-perl-toolchain-summit.html and http://blogs.perl.org/users/joel_berger/2017/05/perl-toolchain-summit-2017.html. They even hold meetings about twice a year, or so. Maybe you want to discuss with them or possibly even undertake to work with them.
