Can you turn Archaic items into tech / analog items?

[VampByDay]

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?

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.
