question about public key usage

Is it possible to have 2 public keys with different expiration dates for the same user?  I created a public key a couple of years ago to be used to exchange documents with vendors for a batch processing account.  That is working just fine.  A new vendor wants our public key but requires the key to have a shorter expiration date.  I don't want to distribute a new public key to existing customers.

Thank you.
