Stop Loss Securities as Savings/Emergency Funds safe?

Is it safe to treat stocks and ETFs in my brokerage account as savings and emergency funds as long as I have a significant number of lots with a Stop Loss or Stop Limit Order in place? My Savings Account technically doesn't cover 3 months of expense, but combined with my brokerage account it does. Is it safe to be have 1 month in savings and 2 months in stock/ETF with stop loss orders in place that if exercised equate to 2 months of expenses?
