The fact of the matter is that while Luke did run some interference for Krayt, he had no way of harming Abeloth himself. It's Krayt that did the heavy lifting in terms of damage. There isn't anything that Luke did in that fight that Krayt(or Yoda or any other top tier Force user) couldn't replicate, but the same can't be said in reverse.
To put it bluntly, two Krayts might have still won that fight but two Lukes wouldn't have stood a chance.
