Not too likely.  The biggest I've seen is a 4x40; anything
larger than 2x40 or 4x20 requires 2 44780s to drive it.

If you ABSOLUTELY MUST HAVE 8 lines, 16 characters
per, you may need to look into using a graphical LCD
instead, and just drawing text.  I've never done it, but I
gather it's not too difficult.  In fact, I've heard some people
say that once they got over the hurdle of starting with a
graphical LCD, they use them for EVERYTHING, even
apps which only need text.

As many have stated your best solution is a graphic LCD you can use a
128x64 for this purpose quite nicely. You do have to store your
character data in some sort of memory. Surprisingly you only need 480
bytes. This gives you 96 5x8 symbols for font data. This is assuming
that
1) you don't need custom symbols
2) you don't need anything biger than a standard 5x7 font.
3) you are using the ASCII symbol set from 32-127.
The standard 128x64 controler makes this kind of thing very easy.
you will get 21x8 instead of 16x8 though. If this is not a problem go
for it.  The cost in volume is very similiar to a 4x20 LCD. The added
flexibility though is priceless.
