A conventional 4-20mA junction box contains only a terminal strip and earth strip to terminate field wiring from instruments. A fieldbus (FF) junction box contains additional components like a spur termination board, field barrier, trunk termination assembly, surge protector, and fieldbus terminator. It also separates IS (intrinsically safe) spur wiring from non-IS trunk wiring for safety .Stainless steel field junction box with ten ports for use in hazardous locations.

The typical topology for a segment is the trunk-and-spur topology with a main line or master cable (trunk). The trunk connects the power supplies and communication interfaces located in the control room with the field. One or more fieldbus junction boxes mounted where they are easily accessible provides connections for field devices.
There is nothing in principle wrong with your suggestion of running another spur to the same junction box, that is in effect the same as running a spur from a new box 12" further along the ring! - If the terminals are too small I would replace the junction box with a larger capacity one rather than making another joint in the ring further along .
