I'd also like to point out, any kind of boxing is going to draw attention to yourself.
Some people are going to report you, because they don't understand or don't like what you're doing.

If both of the accounts are not in the same name, that's going to cause an issue.
That is the first thing a GM is going to look at.
If both accounts are already in your name, you're fine.
But if one is in your name and the other is in your wife's name, there is unfortunately a good chance you'll be banned at some point for using both at once.



If you're serious about boxing, take a look at IS Boxer.
There's a trial period, so you can see if you like it or not.
With a ton of support material, especially the videos by MiRai and the IRC on their site.

It works for the majority of games out there.
And compared to the subscription fee of almost any game you'd want to box, the cost is very minimal.

You can duplicate a lot of the features with something like AutoHotKey or HotKeyNet.
But nothing is as powerful (flexible in what it lets you do) as IS Boxer.
And IS Boxer has wizards that run to get you up and going, rather than needing to learn how to script AHK or HKN.
