There's not much bad citizenry in what you are suggesting: the
assigning-RIR problem is a non-problem, and your two sites are still
only going to originate one prefix each (which they would presumably
do even if you had a separate LIR assignment for the European node).
There is zero "bad citizenry" in this, and don't let anyone tell you
differently. It is your netblock, you get to use it as needed. This
is much better than getting another /20 for an EU site that only needs
a /24.
Also, filtering will not be an issue, if you are careful. Anyone who
does not hear the /24 will hear the /20. Packets for the /24 will go
to your US upstream. As long as your US upstream peers with your EU
upstream, and does not filter the /24 being announced over that peering
link, they will send the bits where they belong. Since this is much
more common than the alternative, you will likely have full
connectivity.
Anyone knows who filters these days? Sprint stopped when Sean left.
Verio stopped when Randy left. I don't know anyone beating that drum
any more. (Kinda nice, actually.) I've heard some Asian ISPs do, but
don't remember who.
