The Supreme Court would almost certainly not read any such letters for the simple reason that they have to do with matters that will almost certainly be in front of the Court sooner rather than later, and thus the letters, if read, would give rise to the appearance of a lack of impartiality, whether or not true. A much better use of one's time would be forming and/or supporting a like-minded organization that could prepare and file a so-called "amicus curiae" or "amicus" brief with the Court when these matters get to the Supreme Court.
That makes sense, thank you.
