Can I apply for a Non-Immigrant O visa in Thailand with monthly bank transfers for retirement?

Questions re Non Immigrant O visa applied for in Thailand and then 1 year 'Extension based on Retirement.'

I'm a UK citizen approaching 50 later this year. I've been periodically in and out for Thailand for the past 5 years on tourist visas, visa exemptions and last year on covid extensions. I left TL in April 2022 and will be returning on a TR visa later this month, with a view to a 3 month stay. I then plan to go to a neighbouring country and then come back on an exemption or another TR visa + 30 day extension and leave again.

I've just started transferring into my Bangkok bank, the equivalent of 65,000 baht from my UK account through Wise marked as 'for a long term stay in Thailand'. I intend to do this every month for the next 12 months so I can later apply for the extension based on retirement. I have no desire to tie up 800k THB in a Thai bank for 5 months for an extension of stay based on retirement and keep 400k baht in the account for the remaining 7 months. I would rather invest this money.

My question is, once I have deposited 65k THB per month into my Thai account every month for 12 months , could I then apply for a Non Immigrant O visa in Thailand, being aged 50 and would these deposits meet the criteria to get this visa? I know it should meet the requirements to get the 12 month extension.

I don't want to have to go back to the UK to apply for an O or OA visa there.

Are there specific financial requirements to meet to get an Immi non O in Thailand? ie a minimum balance in a Thailand bank account at the time of application? If so, does this need to be seasoned?

Of the 65k THB I transfer in each month I intend to use it for monthly living expenses, withdraw some for investments and for purchases, so the balance will not grow from month to month.

Thanks.
