The maximum BGP message size is 4096 and there is no padding, so you
would need a heck of a lot of overhead to get another 300+ bytes on
there. I'd say the answer is no, unless you're running this over a MPLS
over GRE over MPLS over IPSec over MPLS over... well... you get the
picture. :)
It's possible that your link isn't actually capable of passing 4096-ish
byte packets for whatever resaon. A quick way to validate or eliminate
that theory is to do some pings from the router with different size
payloads, sourced from your side of the /30 and pinging the far side,
and using the df-bit to prevent fragmentation. Failing that, make sure
you aren't doing anything stupid with your control plane policiers,
maybe try turning those off to see if there is an improvement.
