A couple hundred lines?

It's honestly going to do it it's way. You'll likely have to go through it all in the end and change a lot. If somehow it pulls it off as you would, there's the issue of debugging or modifying it later. You'll look at it and have to figure it out first before you can start. That takes a lot of extra time.

I find it really unproductive and dangerous to do bigger tasks. Basically anything "from scratch" that isn't the basics, you'll regret it like a rake to the face at some point.
