Has anyone made a titanium G Line using aftermarket parts?

Hi all

I remember when Will Butler Adams did a Q+A on here and said that Brompton was not planning on making a titanium G Line. I'm aware there are third party retailers making many titanium parts for the G Line eg you can buy a full titanium G Line frameset here https://tibicycles.com/products/comeplay-hexati-ultimate-titanium-brompton-g-line-main-framesets?_pos=4&_sid=0d95334bb&_ss=r&variant=42051521708087

I'm just wondering if anyone is aware of anyone who has tried to make a titanium G line using these aftermarket parts? Note this is different to the 20 inch trifolds I've seen which are apparently simply scaled up C Line frames, although maybe someone is selling a full bike with these aftermarket G Line titanium framesets?

Thanks 🙂
