How about simply taking a few thousandths of an inch off the bottom of the guard rail with a  file?  As Jerry Glow has correctly noted there are a lot of products that just aren't commercially feasible.

A few thousandths less than Code 83 gets you to Code 70, and a few from Code 70 gets you to Code 55. Which is absolutely prototypically correct, since most "safety guard" (my term, as opposed to "operational guard" intended to guide the wheel) was old reclaimed rail of a lighter section than the running rail. It was also almost never installed on tie plates. So, if your bridge deck is built to scale, the track cleaning block shouldn't touch the guard rails anyway.
