I was in the Special Boat units when we did the acceptance trials on these boats. One of the criteria was the ability to launch Stinger, surface to air missles. I don’t think a TOW would be much more difficult.
One thing about TOW is that you need to keep the sights centered on the target to guide the missile to it, which is why I was talking about mounting some sort of gyro-stabilized platform for the sights (with the user able to control the thing from inside the boat while looking at the target on a display).
PS: thank you for your service!
