The way I would do this now, three decades later.
-Get US PPL with 100 hour total. 50 to 60 of that in PPL training, rest training towards IFR
-Fly back to Europe convert FAA PPL to UK and EASA , get full UK and EASA IR (about 50 to 55 hours) on your PPL.
-Back to the US do the IR, train for commercial and CFI.
-Work as a CFI.
-Work on a Tuna Boat.
-Get UK and EASA CPL. which is a ****E load of work
Going integrated will cost a lot more.
