I really like what you said. Is there a way to do this using CPF OA or SA funds? Are you referring to cash only?
Quite keen to invest it but careful.
Can use both cash and CPF OA for passive portfolio investing, i use my cash and CPF OA for separate passvive portfolio. My CPF portfolio is 30% STI ETF, 30% 30yr S'pore Govt. Bond, 30% CPF Cash, 10% Gold ETF, to be rebalanced yearly - all bought at once using multiple brokerage in April this year. Total returns including cash interest, for last 6 months, is about 4.25%, not bad for half year of doing nothing.
Yes please be careful and learn any investment strategy well, to know the pros and cons and whether the risk and returns meets your objective. Good thing is passive investing does not need much talent to implement.
To start off your learning, read this to know what a basic passive portfolio investing is about:

This is basic stock index ETF+bond passive portfolio - personally i think this portfolio is ok and is simple to implement, though IMO this 2 assets is not diversified enough for me.
Next, read this about more diversified passive portfolio using Permanent Portfolio Strategy:
Permanent_Portfolio
This uses highly volatile 'stock index ETF+long govt bond+gold' and cash to form a low volatility portfolio. You have to learn about why people such as fund managers invest in govt. bonds and gold.
Then you can go to my blog for ideas about local implementation of Permanent Portfolio passive portfolio:

PP strategy is also widely explained in the Internet.
Which ever passive portfolio strategy you use is up to your comfort level. The main thing about passive ivesting is choosing asset allocation and yearly rebalancing. Keep long term running cost low.
I will highlight advantages of passive portfolio:
-No need to monitor portfolio consistently, or pick stocks, or market time entries and exit - this removes a lot of human errors.
-Lower maximum potential loss in major market downturn, due to bond price appreciating during stock market downturns.
-Near market bottom, potential to sell off bonds that are doing well to buy cheap stocks .
-Force investor to buy assets when they are cheap and sell expensive asset to realise profits.
-Long term returns of passive portfolio is similar to that of pure stock index ETF. Stock/bond portfolio has lower risk compared to pure equity portfolio.
-Aim of passive portfolio is for reasonable 'market returns', not for 'beating the market'. IMO, in general, expected long term returns should be 7%~10% per year.
Cons of passive investing strategy?
-When stocks prices are soaring in bull markets and others with pure stock portfolio are saying how they make above 40% returns, passive portfolio with its decreasing bond prices will make less returns at say 20% only - so no bragging rights for passive portfolio holders. IMO this is not a disadvantage, because the maximum loss and gains of passive portfolio are both lesser, so passive portfolio holders suffer less and are more likely to stick with their passive strategy during market downturns.
