Unless you really want barlines at different times in different parts (and I am 
fairly sure you don't), leave the the timing translator and the bar line 
engraver in the score rather than moving them to the staff.  Then you only have 
to make and unmake the change of bar length in one part;  otherwise you need to 
do it in every part, which is tedious and error prone.

Just remember that the last bar has been made double length, so needs that much 
extra filling (i.e. an extra breve's worth in each part).

With those changes, it aligns fine for me.
