I see that this is still a draft and not manageable. I have a similar function myself that I wrote a few weeks ago.

# get candles from the DB
    candles = get_candles(
        exchange_name, symbol, timeframe, start_date_str, finish_date_str
    )

    routes = [
        {'exchange': exchange_name, 'strategy': strategy_name, 'symbol': symbol, 'timeframe': timeframe}
    ]
    candles = {
        jh.key(exchange_name, symbol): {
            'exchange': exchange_name,
            'symbol': symbol,
            'candles': candles,
        },
    }

    # Execute backtest
    result = backtest(
        config,
        routes,
        [],
        candles,
        generate_charts=True,
        generate_quantstats=True,
        generate_equity_curve=True,
        generate_csv=True,
    )

However, the problem is that this would work only on one exchange. With your code, I think the problem is that it is not a pure function, which was my intention for the research module's backtest function.
