You could tread the path of the cornelius...
what i mean is that you brew your standard length of 23 or 25 Litres. your cornie takes 19L and the rest you bottle and set aside - just forget about them.
3 cornies seems to be working well for me Martin - I've got two tapped and in the fridge, with the third used for conditioning. I always have two beers on tap, and i'm building up my bottlebank at the same time. When a drinking cornie empties I have the third cornie ready to replace it and then do a brew again. You get into a rhythm
A couple of brewers i know do this and it's great popping around for a pint and whilst they've only got 2 or 3 on tap, there's a range of other beers bottled up and ready for 'discussion'
I don't know if that schedule would keep up with your prodigious requirements though
