I don't think so. My first attempts for a lua-fontenc are based in a callback which can combine in on the fly fonts of the same family in a "Unicode" font -- combining T1 and TS1 can be done very straightforwardly, but no doubt other configurations can be set up easily. Several years ago, I had to write some code for Omega (for a firm specialized in technical documentation) and this approach worked pretty well without requiring active chars. The fonts were built with a external utility I wrote in Python, but now that can be done inside LuaTeX. My goal was to implement this approach in the lua-fontenc and in fact I posted some code a few months ago to lua-dev. Chao Javier
