Ido not believe there is a limit as long as you don not break form, fit andfunction. It all depends on your assembly. Remember that jumperwires are to be treated as components and they follow IPC standards.

IPC does not specify a certain number of jumper wires to be used on a board. These are modifications required by the customer and it really needs just their approval. IPC will specify though the characteristics for electrical clearance and routing of the jumper wires. I have build for years boards with a multitude of jumper wires and piggy back components.
