What do you think?

I think the cast iron would have been just as bad. Aluminum can be welded easier, so it should be a safer choice. Sounds like in your case, it's beyond repair. It would be nice to see lots of pictures.
Sorry about your troubles. I would not hesitate to use a Scat cast crank. I would not use an Eagle crank, aside from the problem you have, I'm always told Eagle stuff needs more prep, so you pay for machine work on the back end or pay a little more up front for other products.
Sorry for your trouble. Unless you had an oil issue, I can't imagine it was anything other than a material failure due to poor manufacturing controls during casting and heat treating. You can check the hardness and maybe a few other things to see if it was properly treated.
I suspect lots of us would like to buy your block cheap and see what it looks like up close and personal.
