That's an expression which always sounds odd to me. The footwear known
as 'sneakers' across the Pond is, I believe, called 'trainers' here.
But (a) on this list I'll use 'trainer' to refer to one of the
microprocessor evaluation/learning systems and (b) I've never owned
such shoes and nor do I intend to.

Actually, I think the AT is not the best choice for this. I don't
think the disk controller I currently have in the machine handles
single density correctly. And of course it only supports 2 drives,
currently 80 cylinder 5.25 and 3.5" ones.

A better choice might be my TRS-80 model 4. That disk controller
certainly handles single density, although it won't handle the high
density data rates used on 1.2M and 1.4M PC disks and 8" floppies.
It's also a Western Digital controller chip which I much prefer to
Intel-esque ones.I do have a hard disk on it too -- a 3rd party unit
badged 'Cumana'

The size shouldn't be a problem Assuming I am transfering a disk image
to write to a floppy, it shouldn't be much larger than the capacity of
that floppy. 1MByte should be enough.
