Agree with your last. Upping the thrust on the upwind engine would not help at all. The technique is to up the thrust on the downwind engine.

Disagree. The aircraft will yaw into the wind, but crab angle to maintain centerline on approach is actually reduced because of sideslip into the "dead" engine.
Counter the increased yaw with more rudder. There's more than enough rudder authority - think V1 cut.
I believe theoretically, with sufficient asymmetric thrust, crab angle can be actually zeroed out as the sideslip equals the crosswind component. (Although taken to this extreme, other issues may creep up as previously mention such as asymmetric spoolup for GA, etc...)
