If you're only going to use the lenses on Sony E mount, there seems no point in keeping (most of) them. Sony has some native units in 24mm, 35mm and 50mm (all f/1.8 although the 24mm is not cheap). The 85mm is more tricky as the only options are the expensive Batis and GM lenses; but replacing the 35 and 50 with native lenses seems like a no-brainer.
Anybody know anything about the Sony E 20/2.8 lens? It was never tested here at PZ and I don't remember seeing any reviews on major sites (though I'd be glad to be proven wrong), but if it's any good, you could use it in lieu of the 24/2.8.
EDIT: Kurt Munger has done a review of the 20/2.8 in the past. It's not done in the strict routine like here at PZ (Kurt is like this, and his reviews are/were mostly enjoyable anyway) but pretty informative nevertheless:
