Can you still get a Marriage Visa at Savannakhet with just your original marriage certificate?

Nope you cannot. Once the consulates went to online eVisa applications they standardized the process. You also cannot get year-long, multi-entry Non-O visas anymore, just single entry 90 day.

You have to show 400K baht in a thai bank account in your name only or the equivalent in a bank in your country,

It works like this;

You go to Lao. You log into the eVisa online system. You upload the required documents (proof you're in Lao, proof of funds, marriage certificates, letter from your wife asking they issue the visa, your passport). you submit your application & you get an email confirmation. Print it out and take it to the consulate to pay in cash for the visa (between 9-11 M-F).

Then you wait in Lao until the visa is approved, usually 3-5 business days.

Once they email you the approval you print out the PDF file (as it is your visa) then present it with your passport when you stamp back in to thailand.
