I had a fishy reason for doing this (just for the halibut - get it?), but I decided to stove this. I gave the two limpers a range of any pair, two broadways, two suited, ace, most kings and most offsuit connectors. For HJ I took out the part of that range that didn't make a pair on the flop.

Change AJo to AKo and our equity actually goes DOWN a tiny bit.
Change HJ's range to the same as the 2 limpers and our equity goes up to about 16%.
Change the board to 589r and our equity actually goes DOWN about a percent.
Change the board to T62o and our equity goes up to almost 22%.
Add 2 more limpers and our equity goes down to about 7.5%.
EDIT: Our flop equity goes up a couple percent if one of our cards is a spade. It goes up to about 22% if we catch a spade on the turn.
