By the wording of the rest of your message, I think you meant
interdependent, rather than independent.  Juniper is the Perl of
routers, with more than one way to do things, but I don't believe there
is an easy way to do what you're looking for if its even at all
possible.  You might be able to do something with forwarding based on a
policier, but I'm not sure I would recommend this in general.  It might
be difficult to avoid rapid oscillation between the paths.

Perhaps something more along the lines of flow based load balancing,
would achieve the desired result?  Doing so based on capacity or
utilization is going to be tricky.  You'd also want to take into
consideration the return path, asymmetry routing and potential
packet-out-of-ordering issues that may result.
