Don't really understand the strategies behind it. Sending big PQ's via Mail shouldn't affect CPU utilisation but rather the network load on Groundspeaks Mail Gateway. But why are uncompressed PQ's still possible? An uncompressed 500 pq is approx. 3 to4 times bigger than a compressed 1000pq.
Also, if you send them you don't need disk space to store them.

Sorry I cannot deliver another Idea except send them via email and disallow uncompressed attachements
