Can I apply a coat of thinset over my SunTouch, let it dry, then apply another coat before tiling?

Yes. Some tile installers would rather work over very flat surfaces and they prefer this two step method. First they cover the SunTouch mat with a self leveling mortar or they apply a level skim coat of thinset over the mat. Once dry, they spread thinset while applying tile. Many installers secure the mat to the backerboard and immediately apply thinset and tile. This is a one-step method. Both work fine, so it's a matter of personal preference. In both cases, we recommend using the Loudmouth monitor during the entire installation.
