Unfortunately - no. As discussed above, to be eligible for the biggest benefit of being an expat - exclude up to $100k of foreign earned income through the FEIE, you must meet either the bona-fide residency test or the physical presence test.
If you spent a great deal of time abroad, but not enough to meet the 330/365 day requirement, you might consider spending the rest of the year traveling. As long as you are physically living in a country outside the US - the time will count towards the 330 day rule.
Depending on your situation, you may actually be better off financially not returning for the rest of the year (and not working) - as your earnings (sub $100k) will now be treated tax free, but if you return home after 6 months, you will be taxed just as if you never left. However - this requires thorough analysis, as staying for a prolonged period of time in a foreign country may trigger local country tax filing requirements -- these thresholds vary by country.
