Adding a middle name to my current full name

[38guy]

Hi there. I have a question about changing my name and would like a numerology expert to explain something.

My full name (birth name) consists of one name and one surname, By chaldean numerology, the sum of my name and surname gives an unlucky number 38, which is assumed as the unluckiest number in numerology.

I am thinking about adding a middle name (with a lucky number in it) to my full name so that the sum of my name, middle name and surname gives a lucky number, not 38.

I`d like to know if this is a good idea and would this reduce the negative energy of the number 38 ?
And would it influence my life in a good way?

Thanks in advance.
