Apart from the obvious suggestion of "eat fewer pies" the simple fact is that any microlight is going to leave you seriously compromised, having to trade fuel for load.
Our wonderful Engish weather is also going to leave you wishing that you could use your instrument rating.
Rather consider a good IFR capable workhorse such as the 182 which will offer all of the capability that you need now plus a lot more when you realise that you want to do more.
The 182 is still in production, it has been around since the late 1960s so all of the bugs have been fixed and spares will not be a problem. They hold their value very well so if you change your mind later you will not lose a lot of money selling.
