As far as i know there is a number of carriers accepting low timers on the 320 in Asia right now.
With 500 hrs on type you can also have access to the hold pool of Easy with flexy crew, for example...

If you want to do it go for it.
Organize yourself for the worst case scenario and see what comes up after you're done. Now you can only make assumptions...

Opportunity: Asiana Airlines A320 First Officers - Rishworth Aviation
just my 2 cents.
