I believe it was done a few times in the past and it caused more issues than it was worth doing.
Hyosung tried to use the Mikuni Electric Pump  (not made anymore) on the 1998-2001 super early versions of the GV125/GV250

The vacuum pumps used on the 125s flow at 80 litres per hour (80 litres), thats why it is the same pump used on the GV650 carb models.   It won’t cause any bottlenecks to your bike unless the old pump has gone clogged up   (you can open it gentlely, and check inside) , they rarely fail in fairness unless ex-keepers neglected the bike.
