Yep, that should do as well for Moon eclipse... and the method is suitable for folk who do not want to modify things. Since the timer programming must be the same, the change of sequence involves both timers.
However, timer modification allows for a bit more flexibility (number of bursts can be changed independently of number of shots in the burst), and since the amount of mod work is similar, I will still do the mod
PS:
There may be timing accuracy issue with two timer working in parallel for very long photo sessions (photometry over the whole night, exo-planets hunt). Unlikely, but this is not the issue with modified timer, activated by another one.
