I don't think they would have gone much farther than they did. The Romans, being the Romans, apparently did a cost/benefit analysis before they hit Britain. They apparently overestimated what the place was worth. One could argue that Bouddica KEPT the Romans in England. Nero, apparently, contemplated withdrawing because the upkeep was a net loss to the Treasury. While they were arguing about the dishonor of leaving, the biddy attacked. At that point NO Roman Emperor was going to allow withdrawal.

I think the cost analysis approach was one of the reasons the Romans never invaded Ireland, and made no serious attempt to overrun Scotland.

Agricola made a very serious attempt to conquer Scotland, circumnavigated Britain, and found the Orkneys and perhaps the Shetlands, and then was recalled. In recent years a fortified Roman-era trading town in NE Ireland has been found. But the Romans had other pressing business elsewhere. :')
