Use UDP for (small) incremental zone transfers?

I have a dns zone with many dns updates per minute. The updates are
tiny, like 2-3 records, <500 bytes in total.
Currently my secondaries receive a NOTIFY and they do a TCP connection
to request a incremental zone transfer. We know that TCP is "heavy" and
the data I need to transfer is tiny before shutting down the TCP connection.
Is there any way to do incremental zone transfer via UDP and, if the
size is too big (>1232 bytes), fall back to TCP?
Thanks!
PS: I protect everything using TSIG.
