Have you played with Juniper or Riverbed WAN expander/accelerator devices? Have used them successfully with SM and high latency connections.
Budget allowing ... But may be less PIA than manual scripting plus additional benefits they offer.

Nope, doesn't help. The default snapmirror tcp_window_size is already 2mb, which *should* be enough for my site, but doesn't do a damm thing to help.
Again, if you have a WAN link with high latency and high bandwidth, snapmirror/snapvault both suck in my experience. Which is why I'm spending my time doing lrep's by hand to rebuild DR snapvaults.
Friggin sucks...
