As long as they're reasonably similar it should work fine. For MX that 
pretty much means RE-2000 and RE-1300, you have no hope in hell of 
mismatching the new ones (RE-1800x2/4, which require 64-bit JUNOS) with 
the old ones. For some definition of work of course (for all of the 
active redundancy), where in my experience the answer is "it doesn't".
