DigitalZone Counter Strike 1.6/Source with Valve Counter Strike

I wrote a post on Counter Strike 1.7 and 1.8 previously, in which I have mentioned the versions and updates of original Counter Strike releases. You can see that post at Counter Strike Thread

You might have seen many skins and models in Counter Strike game. You can change weapon appearances and all. Counter Strike such a game where you can edit all the files of the game as you like. The sound files, models, and config files are not encrypted. You can change them to what ever you like unofficially. The only thing is that, what ever you are doing would be only for you and would not change any one else's look even if you host the server. But there is a procedure to add more sounds or looks to the game if you are hosting the server. These modifications can be done by the plugins and addons.

Coming to the DigitalZone's Counter Strike 1.6 and Counter Strike: Source. These can only be modifications of the game and may be taken as completely same game technically. And you are asking about this game's feasibility in playing on Steam, it is possible as long as only the sounds, graphics and models are changed. If you have the same dll files, which are the core for steam to decide what game is yours, you dont need to worry. I have not seen the game by myself but have found from some one else. So, what I wrote here is what I thought about it and I may be wrong. Don't take this as authentic.

If you want to share some information about this, you can comment to this post which would be helpful for the coming visitors to get a cleat idea on what are the changes in the game and what is completely same.

And if you want to ask which game should to try. I cannot answer as I have a different view point than yours. So, just try to explain what you liked and what not.
