Does your debugger utilize debug.getinfo and debug.traceback?  If so,
could you replace those functions at run-time with ones that remap the
file names?  It may go roughly like this:

local old_getinfo = debug.getinfo
function debug.getinfo(...)
  local t = old_getinfo(........)
  if t.source:match'^@.*%.preprocessed$' then
    <read source file or byte code with specially encoded source/line
info in comments or debug info>
    t.source = translated_source
    t.currentline = translated_line
  return t
