MPG will depend on your engine, how heavy etc but could be quite low --- 10... 12 or so maybe on a heavy diesel.... Fuel economy isn't the reason to get one - some are built on truck/coach chasssis.
I would suggest that the conversion would be a very serious job - not just the steering but all the instrumentation/controls/fittings built around the driver... and may even make the vehicle less attractive for future resale for two reasons - going to mainland Europe you'd want LHD (and it really isn't so hard to drive it in the UK) and the DIY nature of the conversion - however good - might put some off.
But good luck whatever you decide, and if you do "go American" you should get excellent equipment as you rightly note!
