Nice start - you're brainstorming, thinking ahead.
My suggestion, go paddle, stay dry, AND spend
a good deal of time - just sittin' down AS you
might after getting soaked due to a mishap.
Carry something large to change upon - space blanket, etc.
Banks are snow covered, icy, wet, muddy, full of reeds.
Laying "something" underneath while changing, helps.
Experiment
Attempt to actually completely change clothes,
strip all the way down, feel the cold wind,
and re-dress in what you brought for back-up.
You'll quickly begin to understand what you
brought, how you packed it, what you might need,
want, desire - and didn't bring.
Extra pairs of dry socks are godlike.
They also work as extra mittens in crisis.
Extra dry hats and gloves. Triplicates if solo.
Dunk-1st set wet. Recovery-2nd set wet gathering/ sweating.
Then comes body fuel - food = warmth = metabolic rate
Hot liquids help immensely and thermoses (plural) help.
Fires take LOTS of time and work; in the cold.
Boiling water takes a pot, melting snow takes a pot.
I'm a big fan of solid fuel Esbit Stoves in Emergencies.
A small metal cup, hot water, dried soup, tea.

All this involves sitting/kneeling down - on something.
Then I usually want 2 of them, one to sit upon,
and one to wrap myself, or stop wind.
I hate cheap mylar stuff. It's noisy, it rips, its small.
Prefer stuff with grommets, build wind block, etc.
String, cordage, dental floss, extra shoe laces, etc.
