Of course you can, but this is not what this thread is about.
We are talking about _alpha_ transparency which is something completely
different.
The way you did it, is exactly the way it is done with GIF "transparency"
which in fact is just a "cut-out" and no real transparency.
This way you have artefacts around the letters that will show up when you
put them on a photographic background.

BTW: You don't need an extension for header replacement. This can be done
with simple TypoScript.
