You can do DTV as a remote worker. There is a Facebook group for it. You have to apply on a Thai embassy and obviously outside Thailand. It’s gives you 5 years and you’ll have to leave the kingdom or make extension every 180 days.
They gave me hard time in Tel Aviv beginning of August although I had all documents as a remote worker. I ended doing it in Taipei which was a much better experience.
It wasn’t clear when I asked but they might be able to do it together just don’t forget the wedding certificate. Better to email them Did they told you 1 or 6 months bank statements?
