"Alternative" Cable

I still don't get any support for this idea. One of my friend, which is financially strong connected, said that it won't financially be feasible!! So, what do you think? Isn't Malaysia-Singapore-Indonesia market large enough to have a good business with this? Learning from Hengchun earthquake, do we really need route diversity ? Of course, there is "oversupply" on the northern route (EAC-C2C, APCNx, etc.) but is there no enough reason for telcos/companies to buy capacity on this route ? :-D
