The big problem is that Taiwan doesn't spend nearly enough on its military, soldiering is a low status job and morale isn't high. Simply put, the society has to become more militarized to survive. I also have doubts that the 'mass invasion via a few possible beaches after 3 weeks of obvious preparation which allow Taiwan ample time to mobilize its reserves' is the only relevant invasion scenario. At the very least, paratroopers can play a major role, and I can think of a few other ideas to spice it up. These can be defended against if Taiwan is seriously motivated - that's the big question mark.
