Oh yes, it has been done quite a lot of times....
All you really will have to do is:
- Make a snarebed, the shallow (2 mm is a good standard figure) indentation or dip that is located on the bottom bearing edge of the snare drum shell and centered under both the snare release and the butt plate, between two lugs.
If you don´t know what shape, search google and you will get lots of suggestions.
- Get a strainer, a butt-end and some snares in a width fitting to the tom of your choice - and mount them. Buy a new bottom hoop - or make holes for the string to the snares to pass through. Don´t forget also to buy a snare side head - this will be a lot thinner than the one already fitted to the tom.
If you also want to cut down the depth of the tom, you will have some more points to consider in order to get a professional-looking result. The vent hole must either be removed, meaning a large part of the shell to be cut off - or hidden in some way.
I, and a lot of other people, has done it to a 14x8" Premier tom.
Here is a pic of mine:

Other people use 13x9/10/11 or 12x8/9/10 toms as donors, often cutting them to a little under half depth, thereby eliminating the vent hole and creating a nice solution while keeping the original finish.
Here is a thread on our danish forum - in danish of course, but the pics tells the story just fine, I think.

Good luck!
