To begin explaining this mod to someone who may know nothing about Beta Minecraft is like trying to explain Minecraft to someone that has never played Minecraft. This mod is unique, it is intentionally built on an old version of Minecraft. Why Beta 1.7.3? Because that is considered to be the golden age of Beta, or for most, the golden age of Old Minecraft in general. We believe someone has been lost as the game has developed, and part of the goals New Frontier Craft has is to revive those aspects of the game that has faded... Yet is also has intentions of bringing something new to Old Minecraft, to make you feel new again to the game. I could go on, but I would just be repeating the front page of the wiki. Interested? Check it out!

I used to love Beta 1.7.3. It is without a shadow of a doubt the best Minecraft version to date... but I just don't have the time to play anymore sadly. I'd love to play this mod and try it out, because a mod for Beta 1.7.3 that pretty much revives the version sounds great, but its not enough yet to get me back to playing it.
What I'd suggest you add to the mod, because I have in fact been in the Minecraft scene since Indev (someone should make mods for that with its unique terrain generator!!) and been in the modding scene since late Alpha...
what you should add is a hunger system similar to 1.8 but with a seperate stamina bar because simply getting hungry from running is stupid... if anything at all that'd make you thirsty... Just things like stripmining and running for ages should drain your stamina and you need to rest for it to automatically refill, and the refill depends on how full your hunger bar is... and your hunger bar serves only the purpose of allowing you actual health to regenerate. And if your stamina is empty, you get a mining fatigue like effect where you just cannot run anymore and mine at half the speed. And speaking of running, that is in fact the other 1.8 feature that I would bring into 1.7.3 Beta...
The real reason why Beta 1.8 sucked was essentially the broken enchantment system which just required ages of mob grinding, and the horrible new map gen from which the game still hasn't recovered yet. And the loss of concepts like the Skylands and the Farlands. I think if it is possible you should make the maps a bit smaller so the farlands can actually realistically be reached in about 1-2 weeks of playtime, if a player wants to travel that far. And add some unique stuff to the farlands on top of that. Beta 1.7.3 was just so promising... best version to build mods on. If only it would've already had the hunger and sprinting and decent enchantments of nowadays.
