Not really
ETC DAG is also over 4GB and pools not accepting the E3s
I cant mine ETC on
https://etc.ethermine.org/ as example. All the ASICs are marked with X
The only way forward with a antminer E3 is to find a new coin or not too old coin that runs on Ethash Algorithm to mine, they should have less mining difficulty and enough room for 4gb miners like E3, go to Google and find answers am sure there are many coins running on Ethash Algorithm
