Modification Modding resin heels

Hey Y'all,
I have recently fell in love with my minifee Ciel. Like any doll collector, shoes are a mission. However I feel it's even more difficult for my girl. She is on the Moe line body and she has a couple of shoes. I however fell in love with the colored resin heels that fairyland released. And of course they do not fit the Moe feet, even though I bought the mint ones.

I'm wondering if there is anyone who has worked with resin who could make them shorter on the sole bottom and maybe trim the top line of it.

 

I was hoping to keep the moe feet proportions and exploring all options.
