If you don't want to have to drill holes or mount and hardware you could do the following:
1) Take the top head off
2) Place tennis racket string in close, horizontal rows across the suspension ring leaving a few inches of slack on either end. The more string, the more snarey so experiment with how wet of a sound you want.
3) Place the top head and rim back on over the tennis string, keep the string fairly tight.
4) As you tighten the top head down make sure the string is kept tight. I suspect the flesh hoop on the head will "grab" the sting and keep it tight as you increase the head's tension but having never done this myself I can't be certain.
6) Trim any excess tennis string from the ends if so desired for a cleaner look.
5) Voila! You should now have a jimmy-rigged pipe snare drum.
Of course, you cannot adjust the tension of the top snares much and you cannot turn the snares off without removing them but if you want that kind of control you'll want to get a true pipe band snare drum. The sound will also be less bright due to the top snares being cable/gut-like.
If you wanted to get real ghetto you could always take a set of wire snares from a drumset/concert snare drum and duck tape the snares to underside of the bottom head.

Without any tension on the snares the sound would most likely end up being way too loose for a pipe snare sound.
