Not without defining your own type to cast to.

The behavior of lexical_cast is limited to what the stream input functions
do by default. The operator>> for int will parse the "0" if presented with
the string "0x16".

On the other hand, there's nothing preventing you from using lexical_cast to
cast to another type, in which case you can make it do anything you want,
since it will call the operator>> overload for that type.
