Yes, you could still copy and paste from stereo into a fresh multichannel sequence.
If you wanted to route to outputs other than 1-2 you’d need to sort that all out manually via the Audio Track Mixer but it’s easy enough to do – assuming the tracks have already been laid out sensibly. If you’ve got elements that you want to separate that are on the same track, you’ll need to move them to the tracks that have the output assignment you need.
By the sound of it, I can’t imagine this is a scenario you’d need to address especially though …
