However if i were to get a new nut, it wouldn't be much different because all the 6 string nuts are for BEADGC and it would be a waste. Should i maybe bring to someone to have the existing nut filled? or should i just try and get a new nut for my new tuning anyways?
Did you check your relief? Probably your truss rod needs adjusting because of the difference in the string tension between the two sets.
It is best to get a properly cut nut when going to smaller strings, but I tuned by Carvin AC50 EADGC for a long time and never bothered to get a new nut and it never gave me any fits. Probably wasn't optimum, but I didn't even have to put pieces of dive bar matchbook covers around the strings to take up the slack.
I think the problem is the truss rod and relief.
