You can use samplicator (small program receives UDP datagrams on a given port,
 and resends those datagrams to a specified set of receivers.
See http://www.switch.ch/tf-tant/floma/sw/samplicator/) 
with multiple instances of flow-capture.  
Run 'flow-capture -w . -N 3 localip/routerip/X'
And then resend netflow udp datagrams with dst IP = localip, and 
dst port = 9994 to localip, port X.
So, you don't need to change
routers configurations.
