Ted,

Approval voting is a reasonable first step. But what do you do about
current top-two runoffs, or primaries in general?
You should be glad to be rid of top-two runoffs - too often, by locking
out the third candidate, they lock out the truly best liked candidate -
think of voter desires as follows, but voting Plurality plus top-two:
45 A
32 B
33 C,B
Here a majority likes B better than A, but most of the B backers vote for
C as even better. Top-two will pit A vs C, letting A win.
BTW - IRV will also let A win - Condorcet will recognize that most voters
dislike C, and recognize B being favored over A.
Most of the highly-regarded single-winner methods discussed here
involve eliminating the primary in addition to changing the ballot and
tally methods.
However, I doubt that primaries (or something fulfilling the same function)
would really be eliminated. I largely blame the failure of LNHarm for this:
Candidates from the same faction have incentive to persuade their own
supporters to truncate, and other voters in the same faction to vote in a
friendly way towards this candidate. If one candidate seems more popular
than other candidates from the same faction, I think these efforts will
be very successful.
Plurality NEEDS primaries. Too often a party will have multiple potential
candidates, and suffer if they split the votes available to back the
"party candidate" in the general election (another plurality problem is
that, even with primaries, a party - or related parties - can stumble into
having such multiple candidates).
With IRV, Approval, Condorcet, etc. voters can rank multiple desired
candidates above undesirable competitors. Here primaries are, mostly, an
unneeded expense. Primaries also work toward a party only offering one
candidate at the general election when a primary loser was better liked by
all the voters.
