As far the last line being justified goes, that happens on a few of the official title crawls. The last line of the first paragraph of the episode II title crawl, the last line of the of the last paragraph of the episode IV title crawl and the last line of the last paragraph of the episode V title crawl are all justified the same as the rest of the paragraph. It seems the rule is when the last line is four or more medium size words big, then it is justified.
I don't care much for the separation of "en route" either, but I can't move "route" up a line, and if I move "en" down, then it creates more of the spacey-ness in the line above it that Trooperman doesn't like.
It's up to him. If he wants me to change it I will.
