That leaves only the MSP-HND-MSP until it gets the HD (777-200ER) w/upgrade on or around 2018-Nov-01. Guess at that point - DL could send all remaining 777-200ERs to SIN for the conversion.
It also depends how many slots are available for the mods at SIN. It could be that only two can be modded simultaneously.
