Is there any way (right now regardless of firewall brand) to re-route
packets from inside of a perimeter, from a specific IP and make it come
in through the outside interface of a firewall, with the same effect of
coming from the Internet?

so you want to send packets out then have them come back in? well..
assuming you have NAT configured you could simply ping an internet
address and the packet will be returned, if you wanted the return
packet to be of a specific ip address then yes firewalls like
checkpoint can modify the ip of the incoming packet (and also to the
outgoing packet) to whatever you choose.
If you can be more specific about what you want to do exactly then i
may be able to be more help, otherwise good luck.

Be more specific. There are several ways to interpret the question and
several ways to answer it, all of which probably depend on the firewall
brand.
I do stuff like this with most of the products I work with though, if I get
your question.

There are some firewalls for which this is not possible, as the
firewall will recognize the incoming packets and discard them.
There are some firewalls for which this can be done provided that
the packets are reflected off of an outside device.
With Cisco IOS-based routers with "Advanced Security" or
"Firewall Feature Set", you can handle it inside the device
by carefully using "loopback interfaces" and selective routing.
I have no information on the capabilities of other major brands.
