You want to ask if you can find packets like that, or you want to
redirect packets like that ??

if your routing table says that a packet needs to go out eth0, then it
will go out eth0...if it happened to enter on eth0 isn't really part of
the decision.

if you are trying to override the normal routing decision, you could use
netfilter targets such as DNAT, or ROUTE...or you could use netfilter
MARK-ing in conjunction with iproute2, or just solely iproute2.
