More on topic: offsetting will work to get a cut that is strong but it also changes the proportions of the font, and that distortion increases the more you offset. The design of a typeface hinges on relative proportions, and while you may or may not notice the difference at larger scales, you probably will lose some of its character at smaller sizes.
This is probably something that most people won’t notice or care about, but there it is. The ideal solution is to probably find a font family that works well at the scale you want, you’ll end up with a truer end result.
Also worth mentioning: “too thin” depends a great deal on your use case. Engraving can resolve features down to about 180-200 lpi in most materials, whereas cutting will depend a lot on what sort of materials and use you’re planning. Quick example: cut a 2” diameter 1/10” thick ring out of 1/8” acrylic: it’ll be decently strong. Try that with 1/16” hardwood and it’ll snap in half along the grain if you put any strain on it.
Just things to consider as you think about how to tackle this.
