Not sure if I understood your question well. If you want to avoid the gateway hop, you can just configure NAT rules with "dnat_and_snat" to do distributed NAT. 'reside-on-redirect-chassis' and 'redirect-type' don't seem to help for your use case because you mentioned your VMs are in overlay, while those options are for VLAN based logical networks.
