Answer to your questions depends on providing us more information. Who manufactured your "starter" sets and what electronics does each engine possess? If you can find it, it might be easier to just provide each engine's Product Number.
If I had to answer based on the data you provided, I would say probably not.
The other thing you should be aware of is that "legacy controller" package (about $350.00) does not include an actual power-pack. You will have to buy another transformer or power supply, probably costing minimally between $100 and $200.
