Is there any issue with "stacking" layers on top of each other?

What I want to do is create a newsletter nameplate consisting of a base 
layer containing a JPEG graphic of a logo, a partially-transparent layer 
above that to screen the graphic and a top layer containing the 
newsletter name in a large and fancy font ala' *The New York Times" & al.

I've already created a nameplate in Inkscape and can simply place the 
resultant graphic but I'd like to do the whole thing in ConTeXt if I can 
as I could easily use the technique in other situations.

I'll wikify any answers.

Thanks.
