I had completely forgotten about divine minion. It is indeed much more powerful and would be a better choice. I just don't usually consider it as I think it is cheesy but in your case it seems appropriate. The only issue that you might run into is the requirement of the wild shape class feature for MoMF if your DM is picky about that sort of thing. But I think it works as the wild shape feature of the divine minion works as a druid. Be sure to look into LA buyoff rules if they are allowed.
