That's a bit circuitous and ignores the LRT convertability of the twinned Port Mann.
Ultimately, LRT systems with radial nodes at:
@ Coquitlam Town Centre (branches to Lougheed Town Cntre/Port Moody, to Pitt Meadows/Maple Ridge and to Burke Mountain); and
@ Surrey City Centre (with braches to Newton and to Guildford)
- linked by one line that crosses the Port Mann - would be best.
They could also share a maintenance yard.
Nice aerial of the area from 2004:
