One more thought related to this, but an issue with modern catalogs which should be addressed even apart from this proposal. In large surveys that use optical fibers to do many simultaneous measurements of objects, there are limits on how close the fibers can be in the field. This means that quasars very close to galaxies are less likely to be sampled. This is a real bias against alternative cosmologies that needs to be addressed. It seems that as areas of sky are sampled multiple times to get repeat measurements there is a need to make sure that all objects are sampled at least sometimes. Is this fully appreciated and is it in fact practiced?
