If, instead of using the bundled software, you get
something like
VueScan [1] then you should be able to acquire directly from the
device (if it's supported; VueScan supports something like 1200
scanners) in your favourite RAW format.
You're still limited by the quality of the optics in the device, but
at least you'll be able to do all your own processing.

I've had others recommend VueScan, but I don't see the Ion scanner
listed there, and it doesn't appear supported yet:

A pity, as most of the Ion scanner's issues appear to be truly
appalling software.
The next best idea appears to be a Nikon Coolscan second-hand from
eBay. (There seems to be a cycle of people buying them, scanning a
whole box of negatives and selling them a year later.) The USB ones
are a few hundred pounds, the SCSI ones are cheaper but jokes about
SCSI requiring black candles and the sacrifice of a goat exist for a
reason.
