Eu gostaria de usar uma forma diferente de um retângulo como símbolo do polegar do capítulo, ou seja, um círculo ou um diamante com cantos arredondados. Isso é possível usando scrlayer-scrpage e uma configuração scrreprt frente e verso? Vi que é possível desenhar formas em LaTeX usando Tikz, como poderia implementar isso com a configuração que tenho?

Se você quiser diamantes com cantos arredondados, adicione \usetikzlibrary{backgrounds}depois \usepackage{tikz}e substitua a \begin{tikzpicture} ... \end{tikzpicture}%peça por algo assim:
\begin{tikzpicture}
\node[inner sep=2.5ex] (n) {\chapterthumbformat};
\begin{scope}[on background layer]
\path[fill=chapterthumbboxcolor, rounded corners=2pt]
(n.north) -- (n.west) -- (n.south) -- (n.east) -- cycle;
\end{scope}
\end{tikzpicture}%
