NO! You cannot return airside without a boarding pass and going through passport control.
...alternatively can I just "forget" about my luggage and somehow claim it the next morning and then clear customs and immigration?
Yes. Unclaimed bags will be removed from the carrousel (after only 3 rounds, I'm told) and yes, you can pick them up the next day.
If you sleep airside in the terminal, don't be surprised if they come by and wake you up asking for ID. But it's quite common and nothing to worry about.
I haven't stayed at the transit hotel for years, as I found the 6 hour limit too short.
I prefer to stay in the city. I understand budget rooms in Singapore are much better than in the past. Even priceline had good rates through last year.
