I not only know of the existence of such, but use them quite frequently. All kinds of glass and resin filters can be used for VC papers. They don't need to be specifically marketed as such like Ilford Multigrade filters. At one time full ranges of glass CC filters were available M and Y as well as B and G, and sometimes still turn up. I often just use a med blue conversion filter like an 82B versus a med green Hoya X1, or for full strength split printing, a 47 blue versus a 61 green (a more readily available 58 green could be substituted). Tiffen does make laminated glass filters, which collect haze more easily, so need more regular cleaning. But reasonably intense multicoated glass contrast filters are routinely available from various leading manufacturers. And yeah, anything but the internal dichroic filters of a colorhead are going to contain some kind of dye, just like sheet filters do.
I really can't understand why people get so hung up about needing this or that "grade" of filter for VC paper. They aren't made for graded papers, few of which exist now anyway; and VC papers present a contrast continuum that can easily be manipulated any number of ways. For example, a deep blue filter will give even more contrast than any so-called no.5 magenta sheet material. Want optimal minimal contrast instead - use a deep or possibly even medium green glass filter.
Of course, each combination of specific VC paper brand and specific developing agenda presents its own personality, so there's simply no substitute for making test strips to learn the truth, case by case. With practice and experience, this all gets very intuitive and fast. But working with filter sheet drawers sounds Mesozoic to me.
