It is impressive how close to the original the looks are. However, I think it is a wise decision not to invest too much time in completely re-creating games which can still be bought and played.
Your already done work should in any case be a great base for all who would like to do something in the direction of "new adventures in Phlan"... using DC abilities which FRUA might not have.
Something that I and others had thought about, was doing a faithful recreation, and then also releasing an all new art set to update all of new art.
In my case, I came to this because I had been working on Secret of the Silver Blades and a sequel. As time went on, I realized that while many of us are nostalgic for these games, there are quite a few FRUA mods that are better and if I was going to really put in a lotmore time, I should remake a better story. I also worked on this because the community voted Pool of Radiance as the one they would most like to see.
I will put together my resources for the Savage Frontier games and release those eventually as well.
