The short answer is no. Even through wireshark. :)
But if you are interested enough to grab packet information, instead of
using the "sh buffers" command you have below, I'd look at "debug ip packet
(ACL) dump" instead.
That's a hidden command for a reason, by the way!

Hmmm, I just had a quick look too, and you're right, there doesn't
seem to be a debug or log option to say "hey! our K-values are set to
this, but their K-values are set to that!" like there is with OSPF
hello parameter mismatches.
So, other than using a packet sniffer (that understands EIGRP), I
don't know of a way to dig deep enough into the hellos to figure out
what we'd need to set locally in order to match the other side.
Obviously a packet sniffer is not available in the real lab.
If you were Macguyver, you might be able to use "sh buffers
input-interface fa0/0 packet" just at the right time to catch an EIGRP
hello packet. But only if you're Macguyver.
Given we don't have access to the BB routers in the real lab, I reckon
it is extremely unlikely that you'd encounter a problem like this
between a candidate router and a BB router. Between two candidate
routers? maybe.
Having said all that, I'd be happy to be shown a way to expose the
K-values being offered up from a "would-be" EIGRP neighbour.
cheers,
Dale
