Increase the size of Hitbox of Players while using Elytra or Swimming

Dear Mojang team

I have been playing Minecraft since 2020 and have seen Multiple Updates Roll out.... but there are some issues when we talk about the field of PvP..... while Flying with Elytra or Swimming, the Players hitbox shifts to the leg of the player, also the Hitbox is much more smaller.... and due to this reason, landing MACE hits is getting harder... I kindly request you to increase the size and shift the Hitbox to the center of the Player, instead of the legs while Flying with Elytra or Swimming
I hope that u will take this into consideration and change the hitbox mechanics soon
Thanks
