It is doable.
If everything you make turns into an ashtray...forget it. If you have above average DIY skils and tools, it is actualy a lot of fun to work with. It cuts, routs and sands pretty much like wood. It is a plastic, which you should not forget. You should use carbide cutters as it is tough on cutting tools. Never force the tool as it will melt instead of burn and you will end up with a mess. It will scratch easily, so you need to keep your work area clean and the corian surface protected, work from the back when ever possible. You need to be able to make an accurate pattern and transfer it accurately as well. As noted the stuff is very expensive.Last, it is very dense, a large piece is heavy and could create a list on the side where it has been installed.
