Yeah you are mostly wasting your time.
Ferrying on the lucrative routes such as trans-Atlantic is a hugely specialised market. You would need to invest serious time and money to become equipped and proficient.
I know of a French C182 Turbo needing ferrying to the US from Wales and the owners are willing to consider PPL's. However, I would not pass you the details as it would be ridiculously dangerous but very tempting for you.
If you are convinced its the way for you then your strategy should be to buddy up with a veteran and fly several times with him for free. They will usually pay your costs only and not the return flight in return for having someone to do the walkaround in the rain, tune the radio and keep a plog. And laugh at their jokes. And carry their bags.
Then when you have bought your own drysuit, GPS, beacons, life rafts etc you *might* be ready to do one solo.
Halfway to Gander in a single with a problem is not somewhere you want to be without a LOT of training and preparation.
There are easier ways of getting hours and money.
Good luck though - if you survive it'll certainly help make you a great aviator.
