why not have TortoiseMerge bundled with TortoiseHg installer?

I very much like TortoiseMerge as my diff tool but would prefer not to install TortoiseSVN just so that I can use TortoiseMerge with TortoiseHg. Is there anyway we can just embed TortoiseMerge with TortoiseHg much like how you embed PuTTy's Pageant.exe and TortoisePlink.exe tools?
