Yes, see < http://lists.gnu.org/archive/html/discuss-gnuradio/2007-08/msg00361.html

I've done this in my personal block making space; it works cleanly and  
well in those cases I've tried.  That said, I'm sure there are cases  
where using GR's template method makes more sense.  Further, using C++  
templates can result in messy and/or non-obvious programming ... I  
don't have a good examples, but I'm confident that these are the cases  
since they're part of the "power of C++". - MLD
