I lengthened my tibias around 6.5cm, went through the surgery 5 months ago.
I think whether it is reasonable will be clear during your lengthening considering that everyone is different.
I can recommend Muharrem Inan at Istanbul if you want LON with monorails. He does dozens of leg and arm lengthening with monorail LON every year with a really affordable prize like 15.000 usd I guess, but I don’t have any idea about the accomodation and the other stuff as I was already living in Istanbul.
Btw I was at your height and became 1,75-1,76.
