DA14683 Secure SUOTA

I'm testing SUOTA on the DA14683 Pro Dev Kit. I'm following these instructions:http://lpccs-docs.dialog-semiconductor.com/da14683_secure_boot/practical...

Since the secure bootloader is burned into OTP, I have to maintain the same private key, that shouldn't be an issue. However, let's say after flashing the dev kit with the PXP_Reporter example with SUOTA, I decide I want to base my project on a different example/demo code, can I remove the pxp_reporter project from the Project Explorer and for example add ble_multi_link. Build, and generate a secure image using the Run make_secure_image script. Then use Android Dialog SUOTA app and flash the newly generated secure image to the dev kit and now have it behave per ble_multi_link?

Thank you for your help.
