Already under discussions are:

ECIP-1025 #66: derived from EIP-212 and EIP-213. ECIP-1035 #78 (needs to be combined with others) is a competing ECIP with this.
ECIP-1026 #67: derived from EIP-198.

EIP-649 does not apply to ETC chain.

The hard fork support wiki page is at https://github.com/ethereumproject/ECIPs/wiki/Hard-Fork-Support. Please create a new ECIP (if not already existing) to accommodate discussions within the community if you prefer some of the above EIPs.
