Sounds reasonable enough.

It will be necessary to configure two service checks for each input.  
One to handle trap processing via 'Advanced SNMPtrap' type service  
check. Second to poll OID of input status via 'SNMP Polling' type  
service check.

It is possible to set dependencies between these service checks so  
you don't get duplicate alerts.

I guess you want to use traps so you get instant notification if an  
input goes offline. What is the reason for also polling each input?
