Yes, you need to build a third FST. You can build a merging iterator that will combine two or more FST traversal streams so that they're in order and then build a merged FST directly, with no extra sorting cost.
https://lucene.apache.org/core/7_1_0/core/org/apache/lucene/util/fst/Builder.html#add-org.apache.lucene.util.IntsRef-T- This should be fast as fst construction is linear with data size (if it's sorted).
