It wouldn't be safe.

You have 6Mbps and if you set up pipes of 2Mbps + 5Mbps you risk
totally messing up the traffic on both if Router 2 starts using up
more than 4Mbps when Router 1 is using 2Mbps.

Is there a reason why you can't have a single Router handle this
setup? Maybe setup VLANs instead of separate interfaces? That way you
could use Queues which would be able to share out traffic. What you
have right now is Pipes which conflict.
