legacy part substitute for old HC05J2

I have some legacy designs that use obsolete 68HC705J2 MCUs.  These are
20 pin DIP  with 2K ROM in a OTP package.  A J1 version is still around but not enough ROM...   I'd like to keep the board and kit but need replacements for this MCU.  I can't find them anywhere - even considered using an J2 SOIC with package converters  but nothing available.

Anyone know of a pin compatible part, or another MCU from that could be substituted?
Worst case, I could rewrite the 05 code and rearrange a daughterboard for another MCU, but that's alot to do.....only minor code changes need for the updates as is..

It looks like it can found as NOS (new old stock).
How many do you need and what would be a good price.
I'd sure hate to see you go to a PIC....

I have not used this service, but you should at least try it:

Enter 68HC705J2 into the search box, and you will get hits. There are companies that buy surplus parts.
