Any idea how i could interpolate two matricies together to produce a matrix that has its XYZ normals half way between the 2 source matricies XYZ normals?

just use
M = (M1 + M2)/2

but the normals will change their length... so you have to transform to spherical coordinates, change the matrix there and transform back to cartesian coordinates to preserve normalization

cant i just renormalize the X,Y,Z normals of the matrix?

In general, you can''t just blindly interpolate between two matrices using that formula.
You might want to check
this paper, but I dont know how suitable it is for real time implemenation
