I asked a question to The Open University guys if they'll accept any random ECTS credits.
The Open University guys confirmed it:
"The most amount of credits we can award towards this qualification is 240 out of 360 (120 out of 180 ECTS). The study can be from any subject and we accept students from around the world and although we have a different credit system, they are the same as ECTS credits.
For more information, please visit the credit transfer website:

"
So, you can try to transfer in all XAMK credits plus maybe US credits from community colleges, self-paced learning, etc.
This looks like a possible plan.
This can be your back up degree plan... i.e. somehow you move to Europe, and you may need a well-known EU qualification.
or you can try to get two degrees at the same time. The Open degree will accept US credits as well. So, you can transfer all of your US credits and get this degree along with your US degree.
