Yes, you can replace the coolant crossover line. Install a barbed fitting and you can use heater hose.

My is leaking at the heater core, so I was wondering if I could run 3/4 hose from the heater to core up to the quick connect, replacing that entire metal line.. I have read that line has to be restricted so it does not blow out the heater core.

The coolant pressure from the pressure cap is far more than the coolant pump dynamic pressure. You won't damage a hood heater core.
thank you
