Arduino Due - GSM Shield

Hello everyone, I want to know if there is someway to use the Arduino Due and the GSM Shield, this question is because I am using the Arduino Mega, for a project that requires more SRAM space (I have tried several ways to variables code optimization), then I see that Arduino Due has 96Kb in SRAM, and is perfect for the project, however it say that is not compatible with GSM shield.

Do you know if is possible to use this shield with Due or if in someday you are thinking to make it compatible.

Other solution may be to increase the SRAM of Arduino Mega, it is possible?

Many thanks for your answsers. Best regards.
