So speeding up the PoS minting and SHOWING via the CPU usage it's actually doing something would be good IMO..

No! That's totally against the whole point of PoS minting.

Besides, it wouldn't change anything in the long run, because an increase in PoS computing power would eventually lead to a higher PoS difficulty.

It wouldn't affect PoS diff at all when averaged over a few blocks.

Think globally. A single client using lots of hashpower to generate PoS blocks with only a few coins in the wallet won't change the difficulty much.
But if you change the official client to speed up PoS minting, then everybody will use the higher hashrate, and then difficulty will rise.

You can mint as much PoS blocks as you have PoS-eligible inputs - and that takes time. A lot of time. (Also, I've got a feeling that PoS diff is static.)
