Yes, someone else has told me this via e-mail, and I will respond to that,
and others have informed me on other 74x replacements.

I already have a prototype made of 4 independant 16 bit counters, and
working with 4 bit counters (74F161) are a pain.

What I really would like is 4 addressable independant 16 bit counters 
running off a single clock (no load register needed) with a common
clear but with individual 'counter-freeze' lines.  There would be an
internal latch to hold each counters value (when the freeze line was
activated) and a single tri-state buffer for the output.

I'll put that on my Chistmas wish list...
