Sure, you could do that. You're using a less well known DOM, which will probably discourage extension authorship somewhat. AFAIK Qt's "v4" is a v8 fork, so scripting performance is probably a wash. It's hard to imagine that the DOM renderer in QML is really much better performing than Webkit, and anyway it's not really DOM rendering that's the slow part in Atom -- VS Code proves that. I don't know what you'd really hope to gain from this, in other words. "Atom is more-or-less just as slow but has a less well known DOM" doesn't strike me as a compelling engineering decision.
