Has anyone attempted to 'moonbounce' or EME ATSC UHF band TV signals, in the 
UHF band allocation?

There are a few problems. 

A typical UHF TV-transmitter antenna will radiate only to radiation
angles very close to the horizontal plane, thus the communication is
possible only when the Moon is close to the horizon.

Looking at the situation from the Moon, communication is possible only
through transmitter sites close to the Earth's perimeter. There would
be multiple transmitters at the same channel (analog or digital), thus
causing interference to each other.

I would be quite surprised, if you could find a situation in which no
unwanted transmitters are illuminating the Moon and thus the signal
would be recoverable.
