struggling to understand why you need to take the pedals off in the first place ATM - maybe I am mis-reading.
anyway the Alien II is a nice multi-tool. But there in lies its problem.
As an emergency tool kit, I would rather this:
ToPeak Survival Gear Box
For what I laughingly call my workshop

I have a cheap (£30 GBP) tool kit that I picked up from Halfords
Halfords Essential Bike Tool Kit which contains:
- 1 x Adjustable ring spanner for easy adjustment of all sized of nuts and bolts

I have also purchased a
Bikehut Professional Crank Extractor (I would have got the Park Tool version, but they had sold out and I needed it), a
Bikehut Professional Freewheel Tool and a
Topeak Joe Blow Sport Bike Pump floor pump.
This is on top of all my sockets that I have for the car. Anything else I get as and when I need it.
