240VAC does not make 80V DC. The number 1.4141 comes into it.
You seem to be thinking "doubler". This type doubler does not need all those diodes. As drawn you get 112VDC twice.
Work backward from output spec. 60V DC regulated wants 10%-40% extra to cover sag and losses. 66VDC to 84VDC. The AC is 0.707 of that, 47VAC to 60VAC. (Indeed VAC=VDC is safe bet for designing smaller regulator supplies.)
What is READILY available in that zone? First thought is 48VAC (or 24+24), a very popular chunk of iron. Two diodes and two caps make this into +/-71VDC. That leaves very little margin for line-sag and ripple. 25VAC (or 28+28) may be a safer bet.
An extreme DIY-only plan, for 120V land, is a 240V:120V transformer of good current rating (double the VA). Run the 240V winding on 120V. Low-low magnetic flux is good. The "120V" secondary is now 60VAC, making 84V raw DC, a bit high but may be tolerable for a 60V clean output.
