Name numerology does not work. Just look at it, it only works with Roman alphabets. If the theory was universally applicable it would have worked with all alphabets. Can you do numerology with Chinese glyphs?
Stick with the name your parents gave you. In the Shastras the father and the mother are called Mahagurus. After your life, your name is their 2nd most important contribution to you. This is the problem with Mithun Lagna people, always doing funky stuff and the 'in thing'.
If you want to know I'll tell you how this akshara/alphabet stuff works. There are 3 imp factors, Vara (weekday), tithi (Lunar day) and akshara (alphabet). Vara and the weekday lord is connected with your physical well being, the lunar tithi is connected with your economic and general wellbeing and the akshara or the first alphabet of your name is connected with your image, reputation and mental well being (manaas).
If there is a vedha from a malefic on the vara (birthday) or the vara lord it denotes sickness and lack of physical felicity.
If there is a vedha from a malefic on your janma tithi it denotes loss, financial troubles and general troubles.
If there is vedha from a malefic on the first akshara of your name it denotes trouble with your public image, scandals, calumny and quarrels which disturb your mental peace.
If there is a benefic vedha the results are opposite.
Vedha means nakshatra aspects. To calculate vedha you have to use the Sarvatobhadra Chakra. It can be used to calculate the effects of transit or whole life. If you are using it for whole life then the mutual MD and AD of the planets involved will bring the trouble or the benefit.
It's better to rule in hell than to serve in heaven.
