List of underrepresented / non-licensed art tokens / lazy art tokens in major modules.

Just wondering if people are interested in having some help in making their games less confusing, as I have seen how common these things are in $50 modules.  Thinking if I could manage to squeeze a high quality production of substitute representations it would make every roll20 DM happy. So testing the waters if people think it is a good idea.

I think "lazy" is unnecessarily pejorative. Roll20 has discussed the licensing issues that keep them from making tokens for creatures that the licenser provides no art for. I.e. it's a legal matter, not effort-related. Beyond that, the community is probably the wrong place to discuss this, again because of licensing and IP matters, depending on how focussed you intend your efforts to be. I.e. if a module is missing an Alhoon token because WotC has provided no Alhoon art, it is unlikely that you could sell, promote or distribute an "Alhoon token for Adventure X".
