That sounds great and a good 'universal' pack! I might just bookmark it for a future project. If it comes to good use, I'll surely be willing to pay for it, too.
A side note, I don't know if you already are, but also look into publishing these packs on for example the Unity asset store. I personally tend to look there first as a Unity-focused developer. But there, you'd best be off putting a price tag on it if you want to get anything from it.
Have a nice day!
