There are several options for riding now, including I believe a rail one way-bus the other to Carcross, YT. If you mean all the way to Whitehorse, I kinda doubt it. I rode the whole distance in 1981, and the best scenery is on the Skagway end, the ride between Carcross and Whitehorse less interesting. The whole market will be cruise ships. The issue is how much the operation will need to expand to accommodate much larger ships. I assume this would mean a ned for more seats per ship arrival, whether this means longer trains, more trains, more bus options, who knows?
