I'd take it even further: make peer review public and open to all members of that community. Imagine a forum-like discussion anybody can anonymously review any submission and all reviews are public. Becoming a reviewer should still be invite-only and the system should keep track of the reviewer's identity behind the scenes to monitor for abuse, of course. The review can include coarse-grained reputation signals like "has reviewed 100+ papers in the last 5 years". It might be worth embargoing reviews with a fixed time delay before making them public to prevent bandwagon effects and disincentivise review plagiarism tho. The reviewer's identity should be deanonymised too after something along the same time scale as when the paper author's identity is revealed.
