You might be interested in MooX::InsideOut: "This is useful for extending non-Moo classes whose internals you don't want to change, or which aren't hash based."

Other than that, there are several other InsideOut classes on CPAN, and in the core there is Hash::Util::FieldHash, but I've never used the latter so I can't say if it's a good idea to use.
