Bicycle Mechanics - Old and new crank/BB compatibility

I'm just curious and rather than disassemble two perfectly good bikes to try it, I though I'd ask the braintrust.
I have an old Japanese bike (early 80s) with a rather bizarre crank. I have a spare 2007 Ultegra crank (with the outboards bearings) that I would consider installing. Has anyone tried this?

Is the bottom bracket shell bizarre too? If not, it will work.
The crank is a problem because the BCD is something odd like 84, and it's getting hard finding replacement rings. A new Ultegra crank would be far easier to find rings for. And probably lighter.
Thanks for the info, now all I gotta do is get a 25 year old crank off!
