No. You need to get another router. Cisco in their infinite wisdom will
give odd results on some interfaces if they are down. I have seen cases
where the interface is there if it's up but when it's down the interface
is gone as far as SNMP is concerned.

I suggest you open a supprt ticket with Cisco on this odd behaviour.
It's their problem and they need to fix it.
