Can I encrypt the backup file without modifying the engine?

Unfortunately, no.

why not just encrypt the tables?

A backup that is encrypted vs a backup of encrypted tables
is (essentially) "non-compressible" anyway.

My customers have a need periodically to transmit backups via FTP. Those
have to be encrypted. There is no need for encryption in the regular day to
day operations.

Do you have the source to DBISAM ?  If so, then there's a way to access the
encryption/decryption routines in the engine to use them.

I actually have the opposite situation where the tables are
encrypted but the content of the backup is unencrypted
tables.

Unless the size of the tables is too large, consider a 2-step
backup where you make a copy of all tables (encrypting them) and
then do the backup from the encrypted tables. My backup is only
several megs so this approach may not be feasible for you.

Thanks. I think I'll just put the backup file thru a ZIP compress (which
will not really compress anything) with encryption, that should do the
trick.

Simple but effective!  There are versions that have
"superior" encryption levels (but you would need
perhaps a non-standard zip program)
