You’ve stayed 120 days in total in Thailand on visa exemption. There’s no official or written limit, but the turning point is often 180 days in a year without a long stay visa. I feel quite confident you’ll be able to turn around and do one more exemption, but you might risk the IO will pull you aside and tell you to get a proper visa next time.
As mentioned in my comment, you don’t have any guarantee that the income with transactions over sea will work or be approved. Basically you’ll need to work in Thailand OR get an affidavit letter from your embassy confirming your income. Unlike the regular Non O visa, twelve months consecutive transactions over sea is not formally an option.
I think your best option could be in Savannakhet Laos. They’ve started requiring funds seasoned for the Non O marriage visa with multiple entries and one year validity, but for the single entry Non O there’s still no financial requirements. You have to investigate this further and I hope someone with recent experience from Savannakhet will advise you.
It might work and it might not. More and more offices are saying IF you don't legally work IN thailand and make the minimum 40K baht a month salary to meet the monthly income requirements based on marriage extension you cannot use monthly incoming transfers from overseas of 40K baht a month for the previous 12 months. It's just a crap shoot on whether your immigration office will or won't allow it, and they wouldn't allow it on the first yearly extension off a 90 day Non-O because you wouldn't have a year's worth of 40K baht a month transfers <- meaning you either legally work here with a work permit and the appropriate minimum salary, your embassy still issues the income affidavit OR you bank the funds.
I don’t think anyone can give you an exact answer to this question as it’s embassy dependent, but I know people are allowed to use income to prove sufficient funds for the six months period and not required to prove the whole amount at once.
