The ram is a GBA chip, so piggy backing most likely will not work. you would need to de-solder the current chic and resolder a new one.
My understanding is that you can find a slew of pin compatible chips that you could solder there...
What I do not know is if the Operating system can dynamicaly figure out the size of the RAM, or if it is hard codded. In the first case, it would work directly. Else you would need to do some SW work to make it work...

sorry that I can not help more...
On the plus side, with the new version of the software, you have around 18MB of RAM, which is quite a lot!

18 or 8 MB?
