Rav Riskin has suggestions about making it easier for giyur because of the problem with the volumes of non Jewish Russians in Israel.
He has written these in a book. This is the way of Torah.
He has conditioned his suggestions on the agreement of other major poskim.
The information that I have is that he has not actually acted on any of his proposals with respect to Giyur, although, as I mentioned in a previous post, there are a myriad of instances where Charedi Batei Din do quicky conversions which are quite obviously based on marriage considerations!
One of the issues with Rabbi Gil Student’s post is that he doesn’t deal with the suggestions that Rav Riskin puts forward.
Instead of arguing with his suggestions some rabbis prefer to just silence him.
I’m aware that Rabbi Yoram Ullman of the Sydney Beth Din, did deal with some of the proposals, however, I was not in a state to be at his talk. If he has published a Tshuva, or anyone can encourage him to do so and pass it onto me, then I’d be obliged.
If I was Rav Riskin, I’d take my arguments to Rav Zalman Nechemia Goldberg and Rav Hershel Schachter (but that’s just me). If they both gave approbation to one of his suggestions, I’d accept it with 100% confidence. If they don’t then I would not. Neither of these Gedolim have an agenda (although Rav Hershel may adopt the approach of his teacher Rav Soloveitchik and be unwilling to Pasken for Israel specifically)
