First thing to say here is
IT IS NOT ILLEGAL TO KEEP A SINGLE PIG - not advised or recommended, but most definately NOT illegal. I have checked with my animal health officer, vet and the police - so can be 100% certain that this is the case (in Scotland at least, but I really can't see that it would be different for England).
Secondly, you can get perfectly good bacon from a 6 month old pig. Granted, the 'eye' of the bacon is not quite as big, but it tastes every bit as good

Bacon can be made from the belly (streaky) or further up to give standard bacon (where you would normally get pork steaks/boneless chops from)
I'd be tempted to send them both off at the same time (leave them to 7 months if you want, just to let them get a wee bit bigger) and cut one for pork and use the appropriate cuts from the other for bacon and cured pork then make sausages from all the bits left over.
HTH

Edit - me and Oaklands have agreed to disagree and for the sake of peace and harmony (and not getting chucked off TAS) will say no more about "it".
