make Kabaya kit solid?

[MechanovaKing]

I'm new to this paint and mod scene
So. I've been painting up my Kabaya kit to make them look nicer.
And I know some limbs need to part form. Like Star Sabers legs.

but is there any way to make there arm still able to rotate, but anchor them in place?

small machine screws and a really steady hand using a 1/16th drill bit.and if you're really adventurous,see if you can salvage a set of scout class sized elbow balljoints and mix them into this guys arms for even more articulated fun.
