nope, the "combination method" to meet proof of funds is ONLY on "retirement" visa/extensions
IF the extension is based on marriage to a thai it's either all banked money 400K baht OR 40K baht in income (either by using the embassy letter if your consulate issues it, OR by transferring in 40K baht a month each month every month for 12 months before you apply for the extension
