Singapore is 4 hours from HK so might work! Also I suspect that if you book with Cathay Pacific (hub in HK) or Singapore Airlines (hub in Singapore) you can probably book either London-HK-Singapore or London-Singapore-HK for not that much more than London-HK or London-Singapore. Or alternatively, lots of budget airline flights between the two cities too.

But there are also a lot of other possible destinations in the area... Taiwan, Bangkok, KL? And you could also pop over to Macau from HK as well...
