How hard 2 crack address & key if both slightly altered?

[FandangledGizmo]

If you copied an address and private key onto a document but randomly changed 1 character in the address and 1 different random character in the private key.


How hard do you think it would it be to crack?
 

Thanks

extremely gross overestimate 256*256 = 65536 combinations to try -> less then a second on a average computer
