Can do it, but recommended is 5-6. But afaicr Bodybuilder pushed 3 inches and is quite fine, so yes it's still possible but usually will depend. IMO proportions would still be your limiting factor, if you have short tibias and lengthen at that and be within the range of proportion for tibia:femur, then go ahead if you can. I personally have long tibias, short femurs(still longer than tibias) and a long torso, so my calves look quite big, so I plan to do this surgery on my femurs.
Hard limit will be as long as your tibia is still shorter than your femurs, if you go past that, it'll just look very weird esp considering it's very rare to have longer tibias than femurs. In fact, it's actually not recommended to have longer tibias than femurs:

No matter how much you want to grow taller, minimize the risk of your mobility and plausible joint problems.
