Hi usb.
I tried to send you a private message but i couldn't (you might want to check your settings) so i hope to reach you through this.
I'm an italian modder too and i've tried for the past few years to fully retranslate FF7 using DLPB's Beacause. You can easily find your my project searching for "caledor ff7" on google. The only thing left to do for me is to translate dialogues so yeah, i've already adjusted every window that required a fix and among them there was the shop menu one. Please reach out to me, either through PM here or trough my project page.
