I've been thinking the same thing, so I found the same mini.iso on my local mirror (no download penalty)
Code:
http://mirror.aarnet.edu.au/pub/ubuntu/archive/dists/devel/main/installer-amd64/current/images/netboot/ mini.iso
and did an install to a spare partition. Ran exactly as I thought and gave me a minimal Trusty install, so I'd recommend you give it a shot.
