Yeah,99.9% of the RA dont leave much more space than 5,perhaps 6
coils;
Typically 32 Kanthal at 5 wraps gives 2.4 ohms or thereabouts (value changes as coil breaks-in/age)
And to answer your question,more wraps should actually gives a tad more as you actually have more vaporizing area,flavor should be enhanced some as well.
