Multiple swf for one AS2 game

Hello there,

I am developing the game Wuli Adventure with AS2. Many time I thought I will turn it into a PC game or port it for console if possible. But right now I need to share a free demo with people and since the game may be heavy online, I was thinking about breaking it down into multpile swf… could I have an swf… who would load in the game an others swf each time a new level is reached… that would be also great against pirates too… because even thought a pirate can steal an swf… I will updates these swf frequently since the purpose of the demo is to be improved according to people s feedback
Any ideas?
the game:
