Just like the title says, is there a way to check if an object is serializable, and if not, make it so at run time?

Short answer – no.
Longer answer – yes, using byte-code manipulation, for example with asm. But you should really consider whether this is needed. Serialization is a serious matter (Effective Java has a whole chapter on serialization)
Btw, there are alternatives to binary serialization, that do not require the object implementing
Serializble(as pointed by Jacob in the comments):java.beans.XMLEncoder.encode(..)is the xml version ofObjectOutputStream
