Yes, that is a nice feature. I also like the fact that it results in an extremely small base, and more separation-of-concerns. Someone else can write an sexp to json parser rather easily.
I'm just lazy enough to wish that someone else had already done so :P

It's funny, I've done exactly that recently, with the same goal of getting away from JavaScript with as little cruft as possible. My goal was to make a hackish little language (nevertheless better than JS) and then make a better language on top of it.
Awkwardly, by the time I had a nice reader, I realized I didn't have any particular semantics in mind for the little language! So I decided to work on the semantics I really cared about instead. :-p Although this semantics is still incomplete, the reader is there whenever I'm ready for it. Maybe it could come in handy for Wat.
It's part of Era (https://github.com/rocketnia/era), and specifically it depends on the two files era-misc.js and era-reader.js.
It's yet another read-table-based lisp reader. Every syntax, including lists, symbols, and whitespace, is a reader macro. My implementation of the symbol syntax is a bit nontraditional, because I also intend to use it for string literals.
I specifically designed it so it can run stand-alone, without any dependencies on the rest of Nulan. It takes a string and returns a JS array of strings, numbers, and Symbols. You can easily write a simple function to transform the output so that it's compatible with wat.
You're also free to modify it, though I'm not sure what license to use for Nulan. It'll probably be either the BSD/ISC license or Public Domain.
