What do you mean by "alpine"?
Are you going to have access to water, or will you be melting snow?
Sounds like you will be on snow. Since you don't seem to use poles, I assume you won't be on skis. What snowshoes are you going to be using? Or will you be using crampons?
Also, sounds like you will need an ice ax. Snowshoes slide a lot easier than skis. Do you know how to self-arrest? With snow shoes or cramons on? Will the gloves hold up to long sidehilling with an ice ax in hand?
What are you doing for navigation? Any experience travelling in a whiteout? Is your clothing system capable of keeping you warm enough if you get pinned down? In particular, I have concerns about your gloves, and footwear. The mitts will work well when not moving, but too warm (wet) if used while moving. I don't know how one would keep their feet warm without heavy boots, synthetic booties, or down booties with a dryloft shell.
If not on the East Coast, will you be in avalanche terrain? If so, what training do you have, what beacon/probe/shovel? Have you considered an avalung, avalung pack, or airbag?
Are you going to be on glaciers/icefields? Are you taking rope, harness, prussiks? Have you practiced crevasse rescue? Any training on travelling while roped up? Do you have a helmet?
Other than the feet and the gloves, I think the clothing system could work. But it depends on what you mean by alpine.
