Maybe the controversial option would work for you, do the ENEB double degree offerings that interest you, get an academic evaluation as per WIKI, then apply to HAU for their 3K MBA, you can call it a day as the ENEB offerings will be equivalent to RA Bachelors & Graduate certificate, your $3K HAU MBA would take a year to do.  Total, 1.5 years for the entire thing...

I think a master degree you can sign up for through Groupon will be perceived far less 'rigorous' (to quote the OP) than the OP getting a EU BPS. Plus the ENEB route still leaves the OP with no bachelor at all, and in the US that is a red flag on a resume/CV (has master but no bachelor). However, the HAU MBA is a good option after the OP gets a bachelor if they're looking for graduate degree options; no matter what bachelor they choose, the EU BPS/BSBA or UMPI BLS/BBA (for example). 

One thing the OP (MISin08) should keep in mind is that at 63, your work experience on your resume/CV will count for far more than any bachelor degree major (especially since the average age of person graduating with a bachelor is 23). At this point (age) it would most certainly be about having a bachelor in order to 'check the box' than anything else.
