Yeah, I suppose this would violate the DOM boundary setup for Web 
Workers as well.

I'm having a difficult time of this.

The concept has been illustrated in an SVG proposal for some time:

That proposal only examines possible uses on SVGElement.
SVG documents use attributes quite a bit, where HTML more often uses CSS.

myFrag1.outerHTML == '<b>Hello</b><i>World</i>'; // could be <i> then 
<b> as well.
myFrag2.outerHTML == '<b>World</b>';

{div: ['Hello', {b: 'World'}, '!']};

JSON.toNode({div: ['Hello', {b: 'World'}, '!']}).className = 'greeting';

No quick route to b class = "target".

This is just the usual DOM work:

var greeting = JSON.toNode({div: ['Hello', '!']});
greeting.className = 'greeting';
var target = JSON.toNode({b: 'World'});
target.className = 'target';


The purpose of this work is to do less string manipulation in JS.

Consider these two methods:
JSON.toNode({div: [start, {b: middle}, end]}).className = myGreeting;
parent.innerHTML = ['<div class="',myGreeting, '">', start, 

Node is a bit of a misnomer if attributes and class names are involved,
as those are part of Element.

This is just an alternative idea for attaching the Element.create method 
we've been discussing.
