my current idea is to use "letter-spacing" like this:

.ow {
	letter-spacing: -0.65em;
 	margin: 0 0.25em;
	}
.ow2 {
	margin: 0 0.25em;
	}

<p>I have <span class="ow">tx</span><span class="ow">ox</span><span class="ow2"> </span>go.</p>

which produces text that reads "I have to go" with the "to" overlapped by "xx" in Preview and PageEdit. Obviously, the spacing is going to be sensitive to different font-families and kerning within the font-family itself (if it isn't monospace), but would this even render as desired in actual e-reading software/hardware in theory?

Alternately, is there a better CSS solution?

The easiest way, that is supported by epub2/epub3, is by employing the property "display: inline-block". For example:

<p>This text is<span class="over">overwritten</span> and this is not overwritten.</p>

.over {
   display: inline-block;
   margin-left: -5em; /* or what you wish */
}
