There is no reason that any Sierra peak that I know of can't be climbed in winter or anytime. You can have avy hazard, but slopes are pretty much stable between storms and warm spells. Just need the good gear and determination.
An old pal of mine sought to do the hardest peak in the dead of winter, and so he attempted Mt. Goddard (13,568') several times, to succeed twice. All on skis from both west and east sides. You might even get a first if you can do your research and confirm with pix and whatever, though most will question potentially doctored photos or the fact about being a winter ascent in truly winter conditions.
If you seek good ski peaks, I used to do that, though not very many. Most people won't bother. The registers most likely will be mostly buried in snow, so you can't sign in or read it.
I had a great time skiing into Mt. Lyell (the highest point in Yosemite) and then summiting, one early April, with one questioning the date, even. There's lots of peaks to ski in the far more accessible Northern Sierra, and the weather is more mild.
One big peak with great views can be ridden to the top, done by millions, I presume--Mammoth Mountain (11, 053').
