Well, no, actually, I wasn't thinking too clearly yesterday.  It isn't
nearly as bad as I made out earlier, I don't think.  The problem that I
can see though, is that it in essence gives someone more than one vote.
Here's an example.

Candidate A needs 40 votes to make quota.  He gets 50, broken down as

Now, under your improvement, all 10 votes excess votes that actually have
a second candidate ranked would go to B, even though only 20% of A's
voters voted B.  Would the 40 voters be forced to put down a NOTA option
just to make sure that the fraction they are entitled to doesn't go
to B?

Let's say B had 40 votes prior to the transfer, broken down as follows:

Now, the 10 votes from A transfer to B, and B's 10 votes with a second
preference transfer to C.

I probably haven't gotten enough sleep prior to posting this, but do you
see my point?  The 10 votes could get a long way from home unless we stay
true to many voters' intention *not* to have their vote transferred.
