A few questions about installing TTW 3.2

[Madrias]

Sorry for the vague title, just I couldn't think of any way to sum up the question I wanted to ask in a short enough form for a title.

Now, I understand TTW 3.2 calls for a completely un-modded F:NV and F3 install. Not a problem on F3, I don't have any mods natively for it, so that's completely normal.

However, my New Vegas install has quite a bit of modding done in it. Now, as I said, I know what the video install guide said, that I should have a completely unmodified Fallout New Vegas install, but at the same time, I'm curious as to what would happen if I were to install TTW 3.2 directly into my NV install without removing the mods first.

I know, I know, I'm crazy, it's a bad idea, but that's why I'm asking here, where the devs are active and I can find out what would happen without having to do it first.

I figure it's better to ask here, get the real answer from someone who knows what they're talking about, and make my call from there instead of blindly jumping in head first off of the high-dive, only to find that the water's 6 inches deep and I'm in trouble.

So, to get to my point and ask the questions I'm most curious about:

Is the "Unmodified Install" requirement just precautionary?
Are my New Vegas mods incompatible?
What would happen if I installed TTW 3.2 into a modified NV?
Does TTW 3.2 alter the New Vegas/DLC Master Files?

Your game will be completely broken, and or the installer won't even work.

TTW is a total conversion, we will be modifying the master files at some point.

Ah. Makes a lot of sense, then, why you've set up the installer to require completely clean installs. Also tells me what I needed to know, as compatibility may be a little shaky on older NV mods.

I'll stick with 2.9.4 for a while, then. I know, I know, 3.2 has lots of benefits, but... I'm not looking forward to having to clean out the Data folder right now.
