Personally I'd take her in if that's the kind of snake you want. Have you researched keeping reticulated pythons? I have a 50% dwarf retic female, will probably get about 14+ feet instead of 25+ feet long. A full mainland retic may be more than you can handle if you don't have people that are willing to help once it gets older.
The attitude of the snake is the number one biggest thing that I would consider when dealing with small retics. I'd pick it up and play with it and if it shows any signs of aggression at all I'd pass on it. A stuck shed is no big deal, just get a tank or tub with underbelly heat with a thermostat and crank up the humidity. I'd even put several layers of wet paper towels over the snake until it sheds out. Retics like higher humidity, I keep my humidity in line with my ball pythons, just keep balled up damp paper towels in the enclosure at all times in one of the corners and keep a lid on the tank to keep the humidity in.
Check out this video, this will show you what you are getting into with a big retic. I found a local female on the internet that I really want to get, really outstanding genes, but I don't want to end up with a 25 foot snake, it's not a dwarf.

For sure that snake could use more food. I'd feed it small rats or XL adult mice twice a week until it gains some weight.
I'd also recommend wiping it down with reptile spray a few days after it sheds and then put it on white paper towels and check twice a day for mites. I'd recommend a quarantine for about a week and if there are no mites I'd feel fine with it. Make sure it doesn't have a respiratory infection too, no liquid on the mouth and no breathing problems.
A snake like that is a big responsibility but if you are up for it I'd say go for it!
