As stated earlier, the feel of those particular scales and perp that location might feel odd. That thing has some wild looking pitch at the first fret , i could see how your hand wouldn't cooperate.
FWIW i use a 25.5" on top and a 24.75 inch on the bottom because I like the feel of a Fender for rythym strings and Gibby's for lead silkiness. The combo of those and a 5th fret perp allows me to use a regular Floyd Rose base for a bridge and my finger sits parallel to the 0 fret in the first position, and all the way down the neck it follows the contour of the slant.
multiscale has its purpose ,but there are soo many varieties, finding one that works for you might not be worth the effort.
but hey- you built a nice looking guitar and gave some business to a few forum members. Not a bad deal at all, IMO.
