You should
really consider using MM:S, conflicting copies of SourceHook in the same address space is really problematic. ESTools does this and it causes conflicts with SourceMod.
One thing to do is what Mani does. VSP version with SourceHook embedded, MM:S version without. This works pretty nicely as the API stays the same.
The whole point of SourceHook is to unify hooking (making it easier through macros is just a side effect). If there's multiple SourceHooks, the original purpose is lost
