I don't think so, but you could simply give it a try

From my point of view network link bonding seems like the better (and easier) approach. Create a bond on each host, assign the IP address to the bond, ready to rock. If one link fails, the other will take over.

Depending on the general and network setup, different bonding types will achieve different levels of load balancing and require different levels of support by the network hardware (switch).

Why do you want to / need to avoid bonding?
