Caliper nipple hole stripped

Hi all
I changed my caliper to evo 9 and 350 disc in dec
One of the calipers was leaking from piston so took it off and rebuilt it today
Car was off road for 6 month plus and caliper was in a box
When i was rebuilding today, i opened the two bleed nipples and noticed the thread coming off with it
Did some googling and think it is to do with galvanised rust( sorry if that is not the right term)
Bottom line is, it is leaking and can't put the nipples back
It is an m10 x 1.0 so bought both helicoil and tap and die for it
I want to try and tap it first and if that fails then drill next size up and helicoil
Question i have is, if existing thread is gone, is there any chance the tap works?
I guess if there is no metal then it can't tap or re create the thread
I then thought of taking it to someone to weld it and drill it again but not sure if they will **** up the bleed hole or not
What would you do ?
I am so angry and annoyed and think the issue happened due to no brake fluid been there so the bolt freezed
