Yes, it can be, but if you just need 1080p, SDI converters really aren't that bad. I just picked up a set of BlackMagic Design HDMI to SDI and SDI to HDMI converters for $59 each. They are around $15 cheaper if ordered without the 5V 2A micro-USB power supply (the same one used on many Android phones), if you happen to already have one laying around. A USB cable plugged into a notebook PC would work also.
Just tried them last night by converting an HD camera's 1080i output to SDI and feeding it into the RCA Video-IN jack in the back of our chapel. In the equipment rack, I took the signal from the coax and converted it back to HDMI, then plugged it into one of the building's TV sets on a cart. If you looked close, there was a slight degradation in the video quality, but from 4' away the picture looked great. I'd call it a successful test of something I might use for our next stake conference.
Yes, this is a far cry from HD distribution through the building, but not bad for a few baby steps first.
