Greetings.
Unfortunately those were sold and licensed as appliances with specific purposes.
If it were possible to accomplish what you are requesting, than it would be easy for a 3rd party (who might not have you or your company's best interests in mind) to do the same, and you end up with 'special' device.....
These just went end of sale last year, and will have updates for a least a couple more years.
Best advice I could offer would be to check with your Cisco account team.
