Request for a mod - Wolves

[Shred Monkey]

I've often wanted to make a Beast Mastermind.  But I honestly can't get past the fact that they summon wolves, and lions, and then another wolf.  I'd much much rather have all wolves.  How difficult would it be to create a mod to replace the lions with more wolves?  I don't need any special new wolf, just more of what we have is fine. 

 

I've asked for this in the suggestions, but no luck so far, so now I'm asking here.
