If I would replace Caecilia, then it would be by a version of DejaVu Serif with added weight. If I can find a freeware/open source font editor to easily do that.
One clue I can give you is if the font has a semibold version you can use that as the regular. You just have to do a bit of editing metadata which you can do for free using Type Light 3.2. The link is in the thread and there is instructions on how to change classification on a font to work on the PW.
