Rather than hand-assembling a new character sheet, I decided to use templating and preprocessing stuff that's used elsewhere on the Web all the time. The result is this repository: <a href="https://github.com/astralfrontier/megalos-roll20" rel="nofollow">https://github.com/astralfrontier/megalos-roll20</a> If people are interested in putting together moderately complex character sheets, with examples of custom roll parsing, sheet tabs, and selectively hidden attributes, you can find all of that here.
