Unless I'm missing something,  this would render the peak rating 
meaningless for almost all amateur use  Even SSB  at 100 watts PEP  is 
going to be pushing the 10W average unless making short transmissions. 
About the only thing I can think of that might work would be short 
pulses of high speed digital.
