Hi there!
I don't think it would change my mind at all - I've bought from a seller in China and did not have an issue, really.
Especially if a customer saw that you were well-respected before your travels, I think most buyers might think it was pretty cool that you were keeping it open.
As long as you are upfront about where you are sending from!
I know for me, personally, unless I knew that whatever I was doing wouldn't allow for Etsy-time, I wouldn't be able to give it up ;)
Have fun and safe travels!
