First build. (super simple saber)

[ACon_Artist]

Hello everyone, I have been searching high and low for a custom saber and one day I came across this site. I'm super glad I did.
Now I am attempting my first saber build and I am trying to keep it as simple as possible and in a way that I can add to it later, but I have a few questions..

so far this is my parts list

for the hilt:
hilt style2
blade holder style 4
pommel style 3 v1
pommel insert style 11 (so I can put my button on the end)

this hilt comes out to 9.75in is that too short?

electronics:
Rebel Star LED & MHSV1 Heatsink Module
BuckPuck 1000mA 4-wire
4AA Battery holder

latching switch I ordered on amazon a while ago.

I have 1.5in inside diameter copper pipe scraps I was planning on making a shroud with. Will this work?
Also has anyone had any luck with plastidip? I kind of want a grippy hilt so I was wondering what kind of options I have there.
The last question I had was with wiring, does anyone use any crimp connectors? Just wondering because I am an electrician, and on small electronics at work we often use crimp connections.
Thanks! Any help is much appreciated
