There is a good chance they will grow. I recently cut a bulb in half that had been languishing in a pot for a year with very little growth and both pieces are doing well with new growth. Any cut bulbs I would treat with sulfur to help prevent rot before planting. Al

Al is right. I would add that your elephant ears will like the weather to be as hot as possible, they like lots of nitrogen (manures) and lots and lots of water. Coleus are beautiful planted around them.

I'm definitely not an expert, but I think your bulbs and partial tubers have a good chance. In my area, elephant ears fall into the "you can't kill 'em" category. I'm not sure about where you are, though. I recently pulled out a ten foot section of my EE "grove" to plant dahlias. I pulled up EVERY visible offshoot (a long and laborious task), tilled down 8", added manure, tilled again, and I am still getting new sprouts. They do love the heat (my best ones are planted near the dryer vent from inside the house), and they like humidity, and lots of water. Why not give them a try? If they don't take off, let me know, and I'll send you some of mine - haha...lord knows I can spare them :)

I agree on the coleus, they are a great mix, also looks nice with Persian Shield (a nice deep purple/silver leafed plant).
