Here would be a good set up for thru hole spindle .

What brand is that chuck, and how accurate is it? I'm interested in that setup for my lathe.

That one appears to require a backing plate. It will have the disadvantage of sticking out from the spindle much further than it has to. We or I actually have a drawing of one that screws directly onto the spindle but unfortunately it has a recent copyright date plus is threaded for 1-1/2"-8 and is for an ER40.

I have one of the ones that mymachineshop used to offer. It's threaded 1"-10 and I'm able to use it on the 618. I'm not sure if he still has them though -- I looked on his site and couldn't see them anymore. I got mine several years ago, and have been very pleased with it. Uses ER25 collets.

Don’t know the brand I found my on EBay several years ago. You can do a search for them.

Couldn’t one custom make a mounting plate that you could move the recess for the collet plate behind the threaded hole somewhat to reduce the stick out?

Of course one could custom make a backingplate that could take up the recess , the only problem I see is the recess is not ground precision . Here is Jinping's finest offering , https://www.ebay.com/itm/New-80MM-DIAMETER-ER-32-COLLET-CHUCK-Compact-Lathe-Tight-Tolerance/112352365393?ssPageName=STRK:MEBIDX:IT&_trksid=p2055119.m1438.l2649
And here is a faceplate https://www.homedepot.com/p/3-in-Face-Plate-for-1-in-x-8-in-TPI-9029/206997690
there are many other 3" face plates out there .
Here is another one https://www.ebay.com/itm/1pcs-80mm-...m=132464599314&_trksid=p2047675.c100005.m1851
Really this thing only sticks out 2" , also I found a bay add for a set of ER 32s' for 35 bucks , now I kinda ' wish i didn't go down the MT 2 rabbit hole . Oh well I 'm just getting started , it's all good .

Yes but you can indicate the bolt on adapter in on your mounting plate. This is what I did plus index the mounting so you mount it in the same place

I wish that on the backside of the collet chuck that the recess was not there . And yes of course being able to indicate it in is key . I think a collet chuck that could just thread onto the spindle (like the one Robert has) would be the best . I wonder if the er 32 faceplate and a faceplate would be too much weight for our 6" or would it act like a flywheel ? And if it did act as a flywheel would that be a good thing .

It wouldn't weigh any more than a 3 or 4 jaw chuck.

The beall collet holder doesn't need a faceplate, it screws directly onto the spindle.

My thought is find some stock similar in diameter and the correct thickness to mount to the threaded spindle, machine a mounting plate to mount the ER 32 adaptor to. As other poster said it won’t be as heavy as a 3 jaw chuck. Mine with the Grizzly backplate is way lighter than the chucks
