I think we have tools for that, such as `project-find-file` (and I'm
pretty sure there are several alternatives in third party packages).

I don't know of a tool for that, but I'd be interested.  I never have
400 siblings (more like less than 10), but I jump between siblings very
often.

There could be several notions of "sibling":
- jump from /foo/bar/main/src/hello.c to /foo/bar/stable/src/hello.c.
- jump from /foo/bar/main/src/hello.c to /foo/bar/main/test/src/hello-tests.el.
- jump from /foo/bar/main/src/hello.c to /foo/bar/main/src/hello.h.

Not sure if we'd want to treat them together or separately (we already
have code to switch between .h and .c).
