Not sure - IF it's the same gear box arrangement as the Maestro (NOT the 'in sump' of the mini) then it's possible, but it'd take a lot of work/parts/machining/expense. Can't believe it is though, as I'm sure we'd have heard all about it before now if it was.
Mini/ Metro engine problem is the rear main bearing seal - and crank of course. Maestro engine has slightly different seal problem - it could be useable - one of the suppliers is working on/has already a kit to use this engine - but not inexpensive! Since many want to use a Ford 5 speed gearbox - the obvious answer is to use the complete Ford engine + box - because it's the special A series/Ford gearbox bellhousing that is very expensive. So - avoid that expense and use complete Ford unit!!
it really depends how much modifying you want to do - the mg midget engine and gearbox is the easiest as it is almost a straight swap for the old engine. But the capacity increase is not huge, so you will not notice a large increase in power. look at http://www.minormania.com if you want some more radical ideas!
