I'm sorry, but that's not homoiconicity. I'm not trying to devalue your work (if you're talking about BABLR/CSTML), but you really cannot bolt homoiconicity onto a non-homoiconic language with a layer, because the defining trait is the absence of a layer.

It doesn't look like your real goal was homoiconicity at all, but rather "stay in JS semantics, keep the JS ecosystem, and build structural editing over any language". Homoiconicity is a word you grabbed to borrow from Emacs's fame, but not a requirement you're were ever trying to satisfy. If it was the actual requirement, there are dozens of options that exist already - Squint, cherry, Clojurescript, Scittle, Fennel-to-JS, even Gleam - any of them gives you code-as-data cheaply.
