I reckon you should get some hours under your belt on something reasonably docile before you go out and buy your ThunderShip. Not because of the knobs or levers for the CS prop and gear, as has been said herein amongst the willy-waving, these are not the issue : but simply because driving something with two or three times the power of the aircraft you've learned on, probably much heavier and faster, probably with engine-management requirements which will impose further conditions on your flying (and cost you dearly if you get them wrong), whilst still trying to get used to the hassles of real-world cross-country flying in the UK is asking quote a bit of most people, and IMHO far more tricky than remembering to dangle the Dunlops ...
Just my ten cents, as someone who has done exactly what you say you're intending to do ...
