RSVP-TE is good solution here, if OP wants to put all traffic in RSVP
tunnels. Make sure expensive path is in SPT, but give L2VPN LSPs
reservation priority, so once the link is full, other traffic will be
off SPT and not use that link. Ensuring maximum amount of traffic gets
best possible service.

If OP does not want all traffic in RSVP, rather make SPT where
expensive path isn't used, and just put L2VPN in ERO tunnels using
that link. If this is the goal, then I'd absolutely look into Segment
Routing, unsure if it's yet configurable like this in JunOS, dunno how
far 16.1 is in SR implementation, but worth researching.
