I don't see any reason not to use it, like any other vessel make sure its completely cleaned and sanitized. Not sure what size stopped will fit but you can just put foil loosely over the top to stop things from falling in.
If you don't use a stir plate its probably better to use a container that is very wide (flat) so that the starter has as much air exposure as possible. A big sanitized tupperware container with tin foil over the top works well.
