Glad you agree that 1-3 would be great to see. I assume they would be the most likely.

Im sure the 413 Days chapter was post-timeskip. I think for 413 days it would be closer to 413 weeks more then anything. If you add the 7 year timeskip, and for argument's sake let's say all the time they were together was a little over a year in total that would be about 8 years which is pretty close to 413 days. Even if the 413 days was only the time they were with each other it wouldn't work cause it hasn't been long enough (has to be about 4 years without timeskip). In my opinion, either Hiro Mashima didn't do the maths or he got days confused with weeks. The anime should just change 413 days to 413 weeks in my opinion.
