Charlie,
I don't believe so. The last time I saw ULOR referenced was at the AUSA annual convention in October 2011, 3½ years after the concept first appeared at AHS Forum 64 (and 4 years after the idea was patented).
Those engines look like they were borrowed from a Hercules.
One development that
does appear to be proceeding is
installation of the CH-53K's 7,500 shp GE T408 engine on the CH-47F, in place of the current 4,867 shp T55-L-714A. The T408 - whose heritage includes the T407 prop unsuccessfully offered for the C-130J in the early 1990s - will nearly quadruple the Chinook's installed power from the 1,940 shp YT55-L-5 installed in the original YHC-1B.
