Could we actually see a proper Minecraft LCE port for the PSP now that the source code is out?

I've been thinking about the recent 4J leaks. Obviously, the PSP has extremely limited RAM which is the biggest bottleneck. But now that we have the actual LCE source code do you think it's possible to strip down the engine and create a 'lite' version?

It would be an insane technical challenge to optimize it that much, but having the actual official LCE menus and mechanics running on a PSP would be the ultimate homebrew project. What do you guys think?
