Yes.  You mind what to track Peter Gutmann's changes to cryptlib to
check what he changed over time.  We might be able to merges some
chnages.  Hoever this needs to be done with great care.

No.  It increases complexity.

If you don't want a seed file, you have to live with it.  Your goal is
not to leave any traces but you consider to use the MS Crypto API?
How do you know that there are no traces left then?  The random seed
file is not that sensitive.  It is of course good not to reveal it -
but it is not more a problem than to use a proprietary API.
