You will need multiple fronts and multiple beachheads to be able to lodge in Taiwan. Otherwise, you will not have enough troop to hold on to the initial gain. You will need to do a phase line attack after your Seaborne force had landed and secured a foothold for you to launch anything airborne or air assault.
Unmanned platform will help but will not be enough to do the initial first wave, the frontline needs to be very wide in order for you to succeed and you can't control an area that big with solely unmanned platform.
There are 4 factors you have to established on any amphibious operation.
Sea Control
Security
Support
Troop delivery
A large transport fleet only fill number 4 in this equation. You will need a large support element (From off shore support to on shore support), a large naval contingent, both sub-surface and surface combatant to provide security on the force and enough joint asset to control the sea surrounding the AO (Area of Operation)
China currently has none of them. In fact, for an island the size of Taiwan, I don't even think the US can invade Taiwan successfully if they were to use the entire Asian Asset. The problem with Taiwan is the coast between Taiwan and China provide a very good strategic depth and ROCN is not that incompetent, and they are going to exploit that, on a force level, Taiwan have around 100,000 troop stationed in the West Coast. which mean for China to overwhelm that defence, hey would have to be able to launch an Amphibious Operation that have 3 or 5 times the troop concentration, that cannot be done currently (I don't think even the US, which had the best Amphibious Capability in the world can pull that off)
