Overseeding is very common. You'd do it good by renting a verticut machine
and using that along with the overseeding. But it's not totally necessary.

Is it possible to just throw a bunch of grass seed onto an existing
lawn, one that is not worth starting again from scratch, but that
could use thickening up?

Would I have to throw some soil down on top? I need to be able to
continue cutting it every week. I have around 1/2 acre to do.
