yes, America could still in fact get a large territory. They could get it by force (war), Buy the land, or a treaty. The bigger question however, is it worth doing it. If America wants to get the land by war that just adds to what the're doing in the middle east, and if it's a neighbor next to them (Canada or Mexico) the blood shead could be high because of pupulated cities. As for money or a treaty it wouln't be that much of a risk but it depends on how much money and the details of the treaty.
The answer to whether it would be possible for the U.S. to get such large territorial expansion today is that:
The United States is currently the strongest nation in the world so if they went to war with Mexico, they would defeat them which would allow them to acquire territory.
If the U.S. were to try to get land through negotiation however, it would be quite difficult as countries are less likely to give up land now than they were in the past especially with more knowledge of the resources their lands have.
In conclusion, U.S. expansion would only be partially likely today.
