Sorry for late reply,
any mods you would merge with HTO would typically be older mods. Merging HTO into a major mod would be difficult, but if you understand the basics of modding the game yourself, you could do it with enough effort.

Greetings, you can call me Hal. I am a major fan of the modding community and am impressed by the amount of work and creativity that goes into making such incredible mods for great games, like S.T.A.L.K.E.R. and Half Life. If you're a modder, keep up the hard work and game on. I have released my own great mini-mod for S.T.A.L.K.E.R.: Shadow of Chernobyl. Check the mods tab under my profile.
