Sure Homebrew is an option but not all table allow it.I don't see anything about the character you mentioned that couldn't be better handled by a class specifically designed to capture the character and playstyle you wanted.
I wanted the ability to buff an ally and allow them to make an attack, repositioning of the party when necessary, help action at range.
It also has enough utility with decent spell selection and skills.
Not something that's currently available without multiclassing
