Haha, I knew you'd be wanting a bigger board at some point. I didn't realise it would be so soon though !
Seriously, if you don't want a monster pedalboard, I think Will's suggestion of pruning the pedals is probably the most logical. I certainly understand that floor space is at a real pemium at your place.
As you know, my pedalboard is not small, but as I use it more and more I find myself using fewer and fewer of the pedals with any great frequency. Maybe try and decide on the absolute "must have's", then put up a list of " like very much's" etc.
I am amazed that you find you need 5 dirt pedals, considering that you play one of the best, and most versatile amps on the market.
Maybe it's time to get serious and start trimming !!!
