"I think I could figure out a way to split two chips and re-fuse them as an error chip."

No need to go to all that trouble. Send two chips to the closest chip fixer and he can make you one of each side. They can do PS same as BJ. Little more work, is all.

I have a rather large collection of errors but would not consider buying another at this time. For me the fun is gone out of error collecting.
