I don't have the exact 3gpp requirement in front of me, but in my understanding the answer is Yes. And, AFAIU it has been decided to use the Outbound mechanism for that. I will take a look whether it would require any changes to the Outbound spec, but at the moment I can't think of any. Keep-alives will not be sent in non-NAT scenarios, so I guess one question is whether the Outbound spec assumes there are always NATs, and therefor always requires keep-alives for Outbound flows.
