I think the answer is NO. The spoofer will not recognize such packets
as TCP packets and simply route them.
One could come up with some clever way to spoof such connections, but
if the VPN services include IPSec, then I think there is no hope.

I do not know enough about mobile IP to answer that question; but here is
my best guess.
If the spoofer is located somewhere near the current base station,
which changes as the mobile changes cell locations, and IP packets
are routed from the destination via the current base station, then
spoofing will probably not work.
If the spoofer is located somewhere near the "home" base station,
and if all packets get routed via the "home" base station, then spoofing
can be made to work.
