Please read the docs carefully:-

If u want to add more IP's then what u have to do  just increase the
--every value .
for example:-

iptables -t nat -A POSTROUTING -o eth0 -m nth --counter 7 --every 5 \
--packet 0 -j SNAT --to-source 10.0.0.5
iptables -t nat -A POSTROUTING -o eth0 -m nth --counter 7 --every 5 \
--packet 1 -j SNAT --to-source 10.0.0.6
iptables -t nat -A POSTROUTING -o eth0 -m nth --counter 7 --every 5 \
--packet 2 -j SNAT --to-source 10.0.0.7
iptables -t nat -A POSTROUTING -o eth0 -m nth --counter 7 --every 5 \
--packet 3 -j SNAT --to-source 10.0.0.8
iptables -t nat -A POSTROUTING -o eth0 -m nth --counter 7 --every 5 \
--packet 4 -j SNAT --to-source 10.0.0.9

i think there is no need to add more interface card.
Please correct me if i am wrong.

Thanks
