I've often wanted the same thing:  What's the time-length of given packets
(using various transmission rates), and the inter-packet delays, etc.  What
_is_ 100% channel utilization, in terms of packets per second of a given
size/rate?

From a pcap file full of radio-tap-level packets, can the channel usage be
computed?  (none of the tools I looked at a few years ago could give me a
channel usage indication from an analysis of actual packets (with rates and
timestamps)).
