If the alternator is working OK why not leave well enough alone. UNLESS you want to go back to original appearance.
If so you may be able to supply more voltage to shunt field to get 12V output OR speed generator up. In either case you will have to modify or replace the regulator which is always the tricky part with motor and generator setups ie doing it is easy with manual control - automatic control is a whole new bag of worms. Can and is done though.
Voltage is just a matter of insulation resistance. I would think going from 6 to 12 V should not matter - you will not bother the insulation. Heat is what destroys insulation in most cases.
Do NOT exceed design current. Ohms law and power thus heat always apply.
