I'd say leave things as they are unless you have a problem.

For your case, where random read latency is not so important and you
are only scanning, upping the block size should not change your scan
latencies and it will make the hfile indices smaller (if you double
the blocksize to 128k, your indices should be halved -- you can see
index sizes in your regionserver UI).
