Is there a 4 byte unsigned int data type in MS SQL Server?
Am I forced to use a bigint?

Use these integer data types to hold values for the following SQL four-byte integer data types: The SQL INTEGER data type can hold integer values in the range -2,147,483,647 - 2,147,483,647.
Some DBMSs, like MariaDB and MySQL, allow to create UNSIGNED columns. SQL Server doesn't support unsigned integers.
Unsigned two-byte integer value. Use these integer data types to hold values for the SQL SMALLINT data type, which stores two-byte integer numbers that range from -32,767 - 32,767. The mi_smallint and mi_unsigned_smallint data types hold the internal (binary) format of a SMALLINT value.
The “unsigned” in MySQL is a data type. Whenever we write an unsigned to any column that means you cannot insert negative numbers. Suppose, for a very large number you can use unsigned type. The maximum range with unsigned int is 4294967295. Note: If you insert negative value you will get a MySQL error.
Can you just add/subtract 2,147,483,648 (2^31) to the regular int ? (subtract on the way in, & add coming out) I know it sounds silly, but if you declare a custom datatype that does this, it's integer arithmetic and very fast.... It just won't be readable directly from the table

It doesn't seem so.
Here's an article describing how to create your own rules restricting an int to positive values. But that doesn't grant you positive values above 2^31-1.
