Myself....I like that second photo you posted with the original cut off trunk and using the Blue as the new leader. I don't see it as a broom. I see it having a strong trunk with knarly thick branches. Most fruit type trees I recall don't have an organized broom style. But that's just what I recall....without any research. In my view....I would let the branches grow out. Cut them way back.....Way back each time. Begin a process of branch chop and grow to take natural angular directions like a wild tree that was regularly chop pruned in an orchard. You have the right idea beginning to pull the branches downward like a lot of weight impacted them over time.
I forgot....what is the trunk diameter above the soil line about where that first big branch was cut off at some time?
I don't think you'll need that lower second trunk trying to grow from the soil level. But I do not have the tree in front of me. It could have interesting value....but my first thought is get rid of it and focus the energy upward for rebuilding.
If I cut back further, I'd be inclined to think this way....using A as example. I like B also though. Using the white line and that small growth looking like it is going upward as the new leader. And begin from that point. What I think....

I'd have fun going either way. Very nice material to work with.
