To answer your question, yes!  There are or, were two in the SF Bay area,
and one in Atascadero (on 101 between SF & LA).  I TACed one of the bay
area E conversions last fall.  The other one has not been seen for 10 to 15
years.  All three were modified 15 to 20 years ago, so this is not a newe
idea.  I fact I got the E-Jag setup the former owner intended for "Blue"
when I bought it in 1981. It is still in my back shed in pieces.  

All three of these conversions used the stock E rear crossmember which
makes it much easier to install but leaves the Tiger with quite a "rake"
(ok, I'm dating myself).  To do the job for the maximum effect, a not
insignificant revision of the crossmemer and floorpan would be required to
arrive at ride elevations  and suspension angles that maximize the
performance of this effort.  

This conversion has been praised by the owners but no actual competion has
shown an advantage that I know of.  If your looking for the best ride, the
reduction in unsprung weight is a major step in that direction.  If your
looking for the fast track on an open track, the live axle with a Griggs
type suspension ( Torque arm, 2 bar locating links, Watts link, and sway
bar, all fully independant and adjustable, is going to be very difficult to
beat.  This is approximately what NASCAR uses on all tracks.

If you want the best, close to stock, design, use Dan Walters Torque Arm
and a low mounted sway bar (below the rear end) or a Watts  link to get the
roll center down as far as possible.
