Well, Neko has quite some expertise in this field. He's responsible for developer relations at Genesi. And while bplan and Genesi are still two companies they are also tied quite close together.
Neko really knows of what he's talking when speaking about the Efika.
He answered you quite detailed.
In essence: There is no way to upgrade existing Efikas other than finding electrically and physically compatiblle RAM chips that would replace the both existing ones. And still it would be some kind of lottery and require additional work in the firmware.

About your hostility feelings: I guess there aren't any. Only that most of 'us old morphers' may have the feeling of a way too often experienced 'been there, done that-feeling' (in one or the other way) and thus are not overwhelmed by those approaches. But that shouldn't stop you in general. New arrivals bring some fresh air, some momentum. I guess most ppl appreciate your enthusiasm.
But about the RAM upgrade, as much as I would appreciate that, I doubt it is feasible. I wouldn't waste my energy on it.
