Unfortunately, the short answer is “not really” to both parts.
For #1 you’d need to do it semi-manually with Tools… Structure Editing…. Change Chain IDs (or command “changechains”).
For #2 if you just had individual models (not ensembles), you could spread them out with Tools… Utilities… Tile Structures (or command “tile”). Unfortunately if you try this on the ensembles, the invidual members of the ensembles will be spread out. As far as I know, there is no way just to tile the 2 groupings.
A similar approach is if you had opened the two ensembles as models #1,2 you could translate them apart, e.g. command:
move x 50 model #2
… and then set independent rotation, e.g. command:
The basic problem remains that each individual member (not ensembles collectively) will then rotate about its own individual center, and the ensemble members will diverge from one another as you rotate with the mouse, rather than keeping together as a tight unit.
