I built a mini VP. It is how I discovered the pin that I eventually bought. Now, the VP sits unused; Part of the reason for that is that I had to reload the software (Windows 7) and I"m really not a PC guy.
You will find some nice games to download. And you will find some that are not so good. I played it for several months and got a kick out of it. And then I played one at TPF 2017. It just did not work for me. Why? Because no matter how much you sing and dance you are still playing a 2D machine. There is comparison to seeing that 1 1/16" silver ball blasting back at you.
If you still wish to do this, then start out on the cheap and make sure you like it before you trash that nice cabinet. Just lay your TV down flat, make your hook ups and play it that way for a while. See if you like it.
Here is the other thing to really think about: This is all my opinion, so go with the grain of salt. A lot of people blow out big bucks trying to make their VP look just like a pinball machine. They will take a cab like your TZ cab, lay the TV down flat and add blades to the sides of the cab. Hold this thought.
I am not a tall person so if I stand at someone's full size VP I cannot clearly see what is going on that the back of the play field. And I especially have a hard time seeing that flat disk that is supposed to represent a ball. So, if I were going to build a full size VP using a TZ type cab I would have to build up both sides no of the cab another 6 inches or so to allow me to have a good viewing angle on the play field. Or at least I would forget the blades and set the TV screen parallel to the play field glass.
I don't have viewing problems with my mini cab because I have it setting on an old desk that is the right height for me. All of the above depends on how tall you are but be aware of your viewing angle. And know that you are building a video game and not a pinball machine.
The main thing is to build it as cheap as you can so you can make sure you like it.
Good luck with whatever you decide.
For me, if I ever decide to get my mini cab up and running I would rebuild the cab to look like this:
