Is there a way to kickstart using a .jpa file that is at a URL address instead of a local folder location? Like if I made a backup called mysecretsitebackupfile12345code at location https://myDomian.com/mySecretFolder13245/mySecretsiteBackupFile12345code.jpa, could I use that location during the kickstart process from https://myOtherDomain.com, or does the .jpa file have to be local to the kickstart file?

Sort of. Use Akeeba Kickstart Professional. It has an Import from URL button. Use it and enter the "secret" JPA's URL there. It will download it over HTTP into the server Kickstart is running. Then go back to its main page. The rest of the process is the regular Kickstart experience.
Why not read the file directly over HTTP? Extracting the file requires a lot of small reads. The delay for each small read over local disk is between a few microseconds to a few milliseconds, the median value being in the area of a few microseconds. Doing that over HTTP takes several hundred milliseconds. This is four to five orders of magnitude higher than local disk access. A backup archive that extracts in 2-3 minutes would take nearly four days(!!!) to extract over HTTP. I think you see how impractical that would be.
The import, on the other hand, transfers several MB of the file at a time. The governing parameter for the time it takes to do the import is the network link speed between the two servers. Then it's local file access which is fast.
