Use bare wire, without of an insulation. You may use larger flexible wire if you split the thick wire strand into single wires.
I believe the most hard work will be de-soldering of existing jumper pins. You may heat the pin from bottom side until the top plastic start to melt and you will be able to pull the pin by a tweezers. Don't pull to early and too strong to not pull out the PCB traces. After you clear the holes from old jumpers, place new ones.
Step one. Prepare a thin bare wire from a larger flexible wire strand:

Step two. Bend the wire to insert into the holes:
