Convert Pine Script to Jesse or Backtesting.py

Can you convert Pine Script to Jesse or Backtesting.py script? The pine indicator is simple z-score with a bit of twist. It uses sma, regression and standard deviation. It has multiple parameters on which I want to be able to run backtesting and parameter optimization. So far I only know of those two programs which can do that relatively easily, just need to get the converted script..
Cheers!
