Not really.  A 3K key is roughly a factor of 50,000 times harder to
brute force.  This is such a slender improvement that it's really not
worth talking about.  If 112 bits of effective security aren't enough
for you, it's quite likely the 128 bits of effective security provided
by RSA-3K aren't enough for you either.

Honestly, I see more sense in RSA-15K than I do in RSA-4K.
