Multi-stage Dockerfile Build and copying Conda environment

Currently, I am building these images myself with some slight modifications. I build the following:
sci-py notebook
tensorflow notebook

I have been doing some experimenting with a multi-stage Docker build process, copying folders from 1 Docker image into the next. Let’s say I have the tensorflow Docker image built as desired. Is it possible to create a new Docker Image from a base Ubuntu image and copy the entire /opt/conda directory from the tensorflow notebook into this new image? Will it work? The reason I ask is because in experimenting, this saves over 1GB of image space. I understand this doesn’t address some things that I would have to resolve separately in the base-notebook and minimal-notebook builds (e.g. apt install).

Appreciate any thoughts.
