Is it worth it to use an elite TM on Origin mons marked for remote trade?

I don’t really have any good Origin Dialga or Palkia to ETM, but I do have a few marked for remote trade. Since we only have this small window to get the special moves, I’m wondering if I should use a couple ETMs just to at least make the trades more valuable. Would that be a good idea?

Since it probably matters how many ETMs I have, I currently have 13.
