Personally, I'd strongly recommended you keep the hihats
Secondly: you say you're "still new to drums." I don't want to speak down to you, but I think it's highly likely that, a few years down the track, when you have some more experience, you'll really regret not having a hi-hat (and it's more than that, if you only just started playing. A few years down the track you won't even know how to play a hihat.). My 'ideal kit setup' has changed so many times that I can't even keep count, and some of them have just been ridiculous. Guess what? Now my ideal kit is a four piece with hats, crash and a ride. Hah, funny how that happens. Don't expect to still idealise your 10/14/15/16/24 setup in another two years, or even another two months.
Finally, and I haven't read the thread too carefully, but I don't think it's been mentioned yet: According to your original post, your argument is this: "I don't want to use a hi-hat because my four toms and two snare drums are more important, and I can't fit it all on the kit." Ask any drummer on this board and I can all but promise they will tell you otherwise. The hihat is arguably the most expressive and versatile part of the kit, whereas having a fourth tom adds very little to your voice.
