I did a thing which does that.
It uses the tun/tap device and some rather funky policy-routing
rules to route packets up through a userspace application. The
userspace app performs the delay and bandwidth limitation then feeds
the packets back into the kernel. It doesn't perform packet loss, but
that'll be easy.
The challenge will be working out how to make it go :( It was a
couple of years ago.
