I like this idea, but, how effective would it be if the two IPs were
neighbors? E.g., two consecutive IPs on the same net block?
YMMV ... depends on the blacklist. The "widely used" lists
seem to just list single IPs or sometimes registered netblocks
for the more obvious professional spammers.
But I have had trouble with some less-used lists when a
"neighbor" (unrelated business in the same /24) got
blacklisted for backscatter.
