Well, like I said, yours is more powerful than the DCv1 version, but has harsher prerequisites. I don't think its overpowered, though, if that's what you're asking.
Haft Strike's only prereq is 2WF, and lets you use the weapon as if it were a double weapon. It grants an additional attack at your highest bonus, but with a -2 to each attack in the round. You can only use half of your Str bonus for damage. This would be a good choice for a PC build relying on 2wf, like many rangers.
Yours, to contrast, sacrifices an attack to do damage & a bull rush, and the 3 prereqs are typical of a high-damage fighter build.
So, they're not the same, but similar.
