It's something way beyond our current capabilities. There's some interesting work on "organs on a chip" e.g. arrays of microfluidic cell cultures that allows some experimentation on a combination of a few types of tissue modeling an organ or some aspect of it, but even that's already pushing the state of art and not fully mature at the moment; doing something similar for many (much less all or most) organs is something that doesn't work yet; and these "organs on a chip" are useful because pure simulation is even less mature and is unable to do what these cell cultures can. The goal you state is interesting, relevant, and potentially achievable, but it's still some decades away.
