Also, can't the 135L take teleconverters? Is the pocketable 2x option worth it for space reasons?
Ouch -- maybe not, based on this TDP comparison:
Yes, the 135L can take TCs, but as you found out, the IQ of the 70-200L II is better than the 135L with TCs. Puls it has IS, better AF, etc, which is why the 70-200L II is so highly regarded.
The 135L doesn't play well with TC's. I took a short trip to Kings Canyon NP last summer and decided to just take 2 lenses, my 24-70 2.8 II and 135L to go light. I also took my 2x III TC and borrowed a 1.4x II from a friend. The 135 worked fine at 135mm, but I was very disappointed with the shots with TC's mounted, most were soft. I probably will not do this again.
The 70-200 2.8 II is brilliant with TC's (as without).
