DMK to BKK transfer using shuttle

Hello, I will be arriving at DMK this friday late at night around 11:45pm (so with customs and all its actually saturday around midnight or so). I then have another domestic flight in the morning at 7am departing from BKK.

This gives me ample time to make the transfer, however since I reach at midnight and the first shuttle is at 5am, will this be enough time for me? I'm not checking in any luggage.
