HALs plan of reducing the overall dry weight with this and removal of fixed ballast etc is very achievable. There will be extra weight added with other avoinic...

AMCA is coming in two variants a stealthy version with no external hard points, and a semi stealthy with external ordinance.
So part of what is being wished for is already being planned. I cannot post a link as I do not remember where I read it.

There is an advantage to the single engine fighter deal , namely when the AMCA comes on line we have some sort of infrastrutcure and technical hands so that a private line can be launched alongside HAL line, Hopefully that is written somewhere in the contract if and when it is signed.
