/reload adding resource packs

Hey there, I've been working on a system that allows for dynamic item textures by doing a whole lot of stuff, but. there is no way to reload resource packs in minecraft without f3+t, I've searched for days. If anyone can tell me how I would greatly appreciate it but /reload only works for datapacks. My idea would be to add command arguments!
/reload (type) (specifier)
so you could do stuff like:

/reload datapacks datapack1
/reload datapacks all
/reload resourcepacks resourcepack1
/reload resourcepacks all

This would allow for minecraft mods, datapacks, server owners, etc... to update specific resource and datapacks while the player is playing! meaning tons of new possibilities.

It is fair that dynamic texture and datapack support is fairly specific. But with the commands minecraft have been adding recently I would love for this to go along with it! Much love to the dev team, I super enjoy your game and I thank everyone for reading this! :)
