It seems like this would be better as two laptops: An ultra-compact for carrying in your pocket, and a bigger one with tons of accessories that you carry in a Pelican for work in the field.
If you are climbing a mast or the like, you are probably out in the field with a kit. You probably don't need a laptop that can fit in your coat pocket. You probably want various cables and dongles and mounting brackets for tripod or pipe mount, etc...
For on-call, I'd be tempted to just use my phone. I can set up Android with SSH and VPN, I can use a bluetooth keyboard if I need to type a lot, or if I just need to get in and run some commands to investigate, I can use the on screen keyboard.
