You definitely don't need any more guns
Besides all of the many varmint calibers you mentioned, I see you own an AR-15, which means you also own a .223 And I spy on nice custom Ruger 10-22 there too.
So save your money, and spend it on a good guide or outfitter. You are already set for firearms, for you have more guns than it would even be practical to take on a hunt.
