Trying to make a small sized avatar bundle

[Izziworld]

Hey everyone! I’ve recently been commissioned to make a small avatar for gameplay. Here are the requirements:

1. Has to be able to equip accessories (Hats, Layered Clothing, Etc.)
   (Update: Layered clothing isn’t necessary, but preferred.)

2. Has to be small, preferable having the head below the R15 hip

3. Does not need to be uploaded as UGC

4. Has to be skin mesh

I’m a little lost on how I should approach this, since as far as I know bundles have size constraints.
Maybe the advanced creation from scratch would be better? Not sure what to do, despite reading through the entire ‘Avatar Characters’ documentation.

Below are some pictures of what I’m creating!

This is the size the client would like. The head position is fine with the client!
