Peach brandy - with not quite ripe peaches

[EricTheRed]

Good morning
Received another 30 kgs of peaches - but they are not quite ripe - and not overly large either

So the plan is to wash them, cut off any bad spots and chuck them into a pot of boiling water for a couple of hours.
Then to squeeze the pips out of them - they are too small to bother with trying to cut them all up
Then, bring them back to HT Pectolaze enzyme temp, pitch, rest for at least 3 hours. (overnight)
Take an SG - add sugar to bring up to around 1.06 in 42L of water - pitch yeast
will be done in a 50L drum

Anyone see any issues with boiling them on the pips?
or any other issue?
