On the Airbus, the thrust command is from your hand if in manual, and shown on the N1/EPR gauges if in auto. Very easy to see and assimilate as part of your normal scan - the levers do not need to move. On the '73 as PM I found I was spending far too much time setting and equalising the N1s rather than scanning the other instruments and the PF, that I found it detrimental.
On the Airbus, the auto-thrust will set the correct N1s and only needs a brief glance by PM of the N1s to confirm.
And you talk about having to concentrate solely on the PFD and want the engine instruments on there as well. Without meaning to sound clever, a competent pilot will be able to control the aircraft, monitor the PFD, look out of the window and at the N1/EPRs.
With respect, you say that you have no experience of auto-thrust or fly-by-wire, so really, your comments are merely speculation, based on what you might have heard or imagine. I am confident that if you actually flew Airbus FBW, and were properly trained to do so, you would find it just as easy as I and most others do.
Don't listen to the nay-sayers !
