Stem::thickness is a convenience wrapper for the C++ part.  I think
creating a Guile wrapper for Staff_symbol_referencer::line_thickness
is the easy solution.  Another option is creating a
'absolute-thickness which is not relative to the line thickness but to
the global staff-space, and use that throughout Lilypond for all
thickness measures.
