Yes, I do raise the Dutch - They are very true to the standard.  I have seen both of them(pictures only of germans) and they are much darker.  If you ask any dutch breeder, they will tell you the german stock is not something to breed with, different origins.
As far as crossing the 2 lines - I would not reccomend it.  But, it would diversify your gene pool, but you will have to work to correct the imperfections of crossing the 2 totally different lines.
As of now, to date, if you breed the DUTCH LINES - there are over 5 bloodlines in the USA right now(2008 import, and 2010 import).  So there should be NO genetic issues if breeding is taken carefully, and a line is not lost.  This year I will be breeding an ORIGINAL import rooster to his daughters, granddaughters, and great granddaughters.  I will also be breeding a new 2010 rooster out of the 2008 import rooster.  This should produce some great vigorous chicks in 2011!  In 2012, I will be offering chicks/eggs from the other 3 bloodlines that are in the USA, but there is only 4 hens, and 1 rooster of those other lines, so I am going to have to breed, and cull, and then build up the flock this year.
These new 2010 import birds are out of the top breeder in the Netherlands!  The same breeder that received a dozen of my LF eggs(you can read what was said on my website - front page).
