Re the bear can...

uh..

You realize you can build yourself a barcalounger with
cup holders in snow? Or chair, or..
But... if you wanna carry extra weight... knock yourself out. I'd carry 3 pounds of extra food instead of a bear can...
or another can of fuel to use for the huge amount of
snow you'll be having to melt.

If you haven't hiked big distances in the snow...
I'd highly recommend a late May hike ... there still
won't be hoards out or bugs... but the streams are more
of a concern... depending on snow pack year

Have fun
