If your users can do "memory attacks", seems that they already have the admin password, no ?
I thought about a ramdrive style protection : an exe using a place only in memory to uncompress/store script, and which can be destruct when asked (and if script abort), so nothing can be get. On the other hand, the exe doing all this stuff must :
1) encrypt the added files it store within, or compress it with a modded header (if some players here looked to the old Diablo mpq files, it's nothing else than zip type with another header. Same things with Diablo 2 and Starcraft. Ok, everything is done with an external dll, but at this point, you can have it in the exe)2) it won't allow to "extract" files to change some things within, but only execute them.
3) A "builder" must me created, as it will be needed to create the exe with the specified file, and the command the exe will run
4) find someone to create a such thing 
Advantage of this one is that it would be completly independant of any scripts language
That was my € 4 cents
A last thing : before thinking about the size, it should be interesting to see what size it show after an UPX (exe compressor, with an incredible rate. 2 Mb => 150 kb)
