Regarding your questions, it is not very good to put "statues" of Radha and Krishna on a shelf. If they are not worshiped as deities what is the use of such display? Visitors will get the wrong idea that they are merely decorative figures or idols, that we do not take them very seriously. Why you do not worship them on the altar?
Your idea to publish a booklet of arguments against impersonalists is very good proposal. Do it nicely by mutual consultation with your learned elder godbrothers and godsisters, and if you like I can provide answers for any such questions that impersonalists frequently ask.
