So I played Secret of Mana on the SNES in the past and liked it. Years later I found out it is not as detailed as planned, because of the conflict between Nintendo and Sony regarding the usage of CDs/cartridges for games.
As of today some members of the original team may be still alive and could help to develop and publish their original ideas. Unfortunately the remake is just what it is, even if todays memory and other resources set no serious limits.
I really would like to see a re-remake published sooner or later. If you agree, lets try to convince the right people to collect and/or write down everything related and license it. With some references mentioning the strength of the fan base added, we are probably convincing investors that a (re-)remake might be rewarding for them.
