Am flying 9W BOM-SIN with a 1 hour 5 minute connection in SIN, connecting to SIN-HKG on CX.

I believe 9W will check my bags through but I'll need to stop at the SIN transfer desk to get a new boarding card.

9W lands in Changi T3 and CX departs T1.

Has anyone had any experience w/ this? I'm concerned that
1. 65 minutes is too short of a connection time (even though its "legal")
2. My bags are not going to make it

Any thoughts?
