What does everyone think of this idea?

Hi everyone,
I've been programming in C++, C and ASM for a little while, and I have an idea:
I could create a program which emulates a microcontroller (which, conveniently, uses x86 assembly instructions!).
Plugins can be loaded into the program to emulate certain hardware components (LED board, VFD, anything really).
Any ideas?
