Modpack suggestion. (Creepersedge War 2019)

Hello. I have been using aternos for around a year now but one thing thats always been missing is a good war modpack. Especially the 1.7.10 MCHeli is one mod which has never been part of the mods aternos has offered. I know the modpack doesent fulfill the '...must be made for Minecraft 1.12 and newer. We won't add new packs for Minecraft 1.11 and older!'(I am sorry for turning it on otherwise i couldnt have posted this) bit but why i like this modpack so much is because it has in my opinion all the best war mods for minecraft out there! I have tried to especially add the mcheli mod to the game by making a folder called MCHeli, making all the folders inside of there, making all the folders iside of there, making all the .txt files inside there and copy-pasting all the text into each one individually but i began getting problems with this when i realised that i couldnt make the .class files and so on. I really hope we could get a fix for this, and get the creepersedge war modpack into Aternos even though it doesent fulfill all the requirements because this modpack is very good and would be the first modern warfare modpack in all of Aternos. Anyways, i appreciate the Aternos team and i understand if i cannot get this luxury.
