Pixel Blade w/ Crystal Chamber Wiring to Golden Harvest

I'm just hoping to get some more experienced eyes on my wiring diagram before I start soldering. This is my first saber and I knew almost nothing about wiring/electronics before starting, but I've done quite a bit of research and I think I'm almost ready to put everything in place (barring any dumb issues I'm overlooking).

Here are my major electronic components:
Golden Harvest v3 Phase 4
Keeppower Li-Ion 18650 3.7V 15A 3000mAh Battery
KR Pixel Stick V2 34.75"
5mm RGB LED (for CC)
Switchcraft 2.1mm Recharge Port
16mm Anti-Vandal Momentary Switch (no LED) x1
2W 28mm Bass Speaker

Some questions I haven't found answers for so far:
Is there any reason I shouldn't just use DynaOhm variable resistors for the CC LED aside from internal space issues?
Should I be concerned about heat management for the CC LED?

Any feedback is really appreciated :D
