The answer is a tentative “Yes it is possible”, though likely not advised since that would mean having two tables with identical data structures, a set up not often ideal for relational databases.
You would first need to do
base.createTableAsync and include all the fields you need created. Note: not all field types can be created via script (none of the calculated fields). Then you would batch create the same number of records that existed in the first table using the original field values. Certain field types like attachments would be more difficult to migrate, but not impossible.
