We would like to take the moonlight kyushu train on 26th December.

Note that on December 26, the train runs only from Osaka to Hakata but not from Hakata to Osaka.

No, I don't think so.

I am afraid that there is a very high chance that the train will be booked out long in advance.

or is it any other way?

I found the following service, but I am not sure whether you can use it from overseas and whether you can make reservations for the Moonlight Kyushu. Furthermore, Japanese language skills are required:
