The only possible situation where the connection you describe would function
is when the INPUT SWR to your amp is not good. This is a quite common
method of matching HB amps where their input impedance isn't THAT bad and
the builder doesn't want to bother with a separate set of switched input
matching networks. An external tuner, or one inside the amp, such as an LDG
for example is used to match the tube(s). However, in order to do this,
you have to let the input tuner do it's thing only when you have a good 50
Ohm dummy load on the amp. THEN, after the input is matched, you can switch
in your real antenna & tuner and adjust it for best SWR to the antenna. At
this point, it is essential that the input auto tuner is NOT still trying to
find a match.

Mark,
The short answer is no.
