Can you turn Archaic items into tech / analog items?

So this quote from GM Core seems to hint at the idea of being able to turn archaic items into 'modern tech items' and letting them loose the archaic trait, but it stops short of actually saying that. Is there a ruling (maybe in one of the paizo lives) that I missed?

By spending an additional week and paying half the base

Price of the equipment, you could install the technology
required to apply upgrades, integrate tech like comm units
and environmental protections into armor, and add upgrade
slots to shields and weapons.

There is unlikely to be a clearer rule then the GMC chapter on the exact topic.
Converting Archaic to Analog seems to be very clearly the intention here. Maybe you could ask for Errata to make it clearer, but the purpose seems unambiguous to me.

I ran the numbers a while back, and 1H Melee weapon should translate 1:1 between SF2 and PF2.
With 2H Weapons and Two-Hand the math becomes odd. SF2 just seems weaker.

+1. I'd like to understand more precisely how to count upgrade slots.
For example, I bought an Aldori dueling sword for 20 credits. I spent another 10 credits to remove the "Archaic" trait.
What next?

Very few weapons start with 0 upgrades, so it's safe to say that 90% of the time, a converted weapon would have 1 upgrade.

The aldori dueling sword would automatically gain the analog trait in losing the archaic trait. And it would have 1 upgrade slot by default, and gain successive upgrade slots as normal.

The pattern that I see is that weapons start with one upgrade slot and gain an upgrade slot with each increase in damage dice count.

As for upgrading a level 0 non-archaic weapon, it would follow the normal rules for upgrading an analog or tech weapon. The GM would need to determine the cost of each tier of improvement using other similar weapons as guidelines or the standard cost by item level table.

I could see an archetype built around this concept. You get one weapon for free (per daily prep) that automatically gets one upgrade slot per weapon damage die (thank you Finoan) and your archetype is basically you come from a world that is relatively low-tech, but you somehow got your hands on advance stuff. you still favor the archaic weapons, but have learned to force modern tech into these old-fashioned weapons.

(Admittedly I'm thinking of something along the lines of Horizon Zero Dawn here)

It literally sounds like Numeria :)
