Question Lighting Circuit - 3 feeds from 2 gang switch box

Refer to my attached image (diagram):

I'm planning electrical for my kitchen remodel. I have an existing lighting circuit, 20A with 12-2 wiring from the breaker box on the far corner of my house to an accessible junction box near my kitchen. From that junction box I'd like to run a feed to the wall switch location near my sink. From there, I need 3 things:

a switched line for can lights above the sink
a switched line for under cabinet lighting
an unswitched line for in-cabinet puck lighting

Can I run 12-2 from the basement j-box to the 2-gang switch box and feed all three out from there, or do I need to handle in a different way?

Any advice is appreciated. Thank you,

Brian

Only if you change the breaker to 15 amps but best practice is to not use mixed wire sizes. Someone later might see the #12 and change the breaker to 20a not realizing there was #14 mixed in.

Nuts - that was a typo (fixed now). I would be running 12-2 from the j-box to the switch box (and beyond), NOT 14-2. Everything would be #12 wire. Knowing that, can it be done as described?

Yes. Just remember under 2011 NEC all switch boxes not connected by conduit must have a neutral even if not used. So simplest is to bring power to the switch then the light but your diagram gets that right so no problem.

Awesome. I thought it was that straightforward but haven't tackled a large wiring project since 2007ish. Thanks again for the help!
