Personally, I'd strongly recommended you keep the hihats
Firstly: not having a set of hats pretty well guarantees that you will never play in a cover band, ever. This may not sound like a big deal right now, but trust me, it is. I'd say 75% of my gigs are covers gigs and 100% of my gigging income comes from covers (in fact, my originals band has cost me more than it's made me). It's completely valid that your drumming 'voice' doesn't have to have a set of hats, but almost every other drummer does use one. If you want to recreate other drummers, you'll need the hats.
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.
I can sort of understand your logic, but because you say you're only new to drums I'll say this: It's best to learn the rules before you try to break them. My advice is to stick with the hats, take some lessons and really learn how to play them. You. Will. Not. Regret. It.
