How to pack two EXE application ?

It's not really what I want.

I'm coding a screensaver using Blitz and PB.
The launcher is coded in PB.

/c -> config (PB)
/p -> preview (PB)
/s -> 3D saver (Blitz)

My idea is to remove completely the Blitz console at start.
Without this problem, my saver could be a pro saver.
