LOL....I was waiting for someone else to answer too .

You'd have to work really hard to get too much filler in epoxy and even then it would set, just might not be structural nor hold it's shape. As long as the mixture holds together wet, it should once it's set.

Doing testing is the ideal btw, you get alot less bad surprises that way.
