IMHO you are doing the right thing, but i can advice you a futher
improvement and very important - perfomance boost for your module.

You can do shorcuts shorter:
     in setup_finalize of Catalyst:

        foreach my $source ($schema->sources) {
            next unless index($source, '::') == -1;
            my $acc = "${source}RS";
            $c->mk_group_accessors(inherited => $acc) unless $c->can($acc);
            $c->$acc( scalar $schema->resultset($source) );

You gain very short accesors (which cannon conflict due to 'RS' suffix)
for example

Plus - such accessors works MUCH MUCH faster than $schema->resultset because
->resultset method generates new empty resultset every time and this
operation is quite hard for DBIC (why???!!!).
With this accessors all empty resultsets has been already generated on start.
