I used to share that thought, and I have a font that hangs around called Modded Palatinx that contains a few improvements from the days when it was more important to me that my system be right, than that it be compatible. But nowadays, it looks a bit weak compared to other serifs - more of an acknowledgement of serifs without their meat. It's possible that hi res screens has made me think differently. I'm not sure.

(But in any case, the standard Computer Modern Roman is not my cup of tea. I like more rounded fonts, but its serifs are too strong and dominate the shape.)
