Do two separate query-replaces, one to replace < with [, the other to

I think what you're talking about is:
<\(.*?\)>
Relace with:
[\1]
Or maybe this is what you mean:
<\|>
Replace with:
\,(if (string-equal \& "<" "[" "]"))
This latter option is only available in interactive mode, not when
calling query-replace-regexp from Elisp.
