There’s a Cosmic Fantasy Collection Makuake (crowd funding) campaign going in Japan at the moment. The series spans five games (plus a visual collection) that were released for PC-Engine CD, as well as a Mega-CD collection of the first two games. The project is already fully funded so there may be some stretch goals, it’s ¥5500 for the digital code during the campaign with an expected retail price of ¥6380 when it releases in December, 2022.
Produced by Edia, the same company that brought us two Valis collections, this collection will include the first two games in the series. One difference is there does not appear to be a physical copy, but there are some physical extras available. The series creator is involved.
No word on an international release but it would be cool if a company decides to take on that project. I think Cosmic Fantasy 2 is the only one that was released outside of Japan (Working Designs did the conversion for TG-16), who knows if the usual suspects are willing to translate several JRPGs and distribe it physically or digitally.
