That is not so easy. Actually I started developing Forex Strategy Builder because I was not satisfied from the MT backtester. There are tens of key points and private cases in the backtesting that MT does not care about.
MT leaves all the logic aspects in the hands of the programmer. MT does not check the EA for logical errors. That is why there are so many experts showing good profit in backtest but falls down in real trade.
I'm developing FSB with the intention to make it as safe and reliable as possible. FSB protects you. It does not allow you to make a false backtest. Even if the back test is not 100% reliable FSB warns you.
Makin FSB to MT exporter means the exported EA to include many back testing features. Why to do this? I'm not using MT and nobody pays me to improve MT. If someone wants he can make this exporter. I'll help him. But I'll not lose my time for this.
If you want EA from FSB strategies this is not a problem. I know an excellent EA programmer who will make it for you. But this is not free. As I know he takes $15-20 per hour. I personally do not take even a cent from this.
If you want ask in the forum what EA you what. Someone could offer you to make this EA for you. Of course asking in the MT forums also is not a bad idea.
I'll not refuse any help about the logic of the FSB strategies. If you have specific questions ask here.
