Creating venv with new sub directory inside the main directory consisting of venv

Question

I am working on time series forecasting using various libraries and here is my main folder (which is the root directory with virtual environment) containing sub folder as shown below

Main folder /
     venv / …
     ARIMA / …
     HoltWinter / …
     VAR / …
     Prophet / …

the prophet library has version compatibility issue with ARIMA. So I am planning to create a new venv for the same and open the Prophet directory with new VS code window and new folder structure will be

Main folder /
     venv / …
     ARIMA / …
     HoltWinter / …
     VAR / …
     Prophet / 
           venv /…
           example.py
           …

Before doing this , I would like to know whether its possible to have this kind of structure? (I will be working with Prophet and other TS models separately in vs code)
