SNMP Root OID

When initializing the MIB tree for SNMP, the DC lib initialization function sets the root OID to 1.3.6.1.4.1.MY_ENTERPRISE, which has worked fine. However, I've noticed that when MIB Browsers do an Agent Discovery, they query for parameters in System node, which is not under the root node.  So they don't pickup our products.
 

 Is there any reason why I couldn't replace the DC library's initialization function with my own that sets the root OID higher to capture the System node? I would like the root OID to be 1.3.6.1.
