Changing a rod from casting to spinning is going to greatly change the dynamics of the rod. When building a casting rod, most rod builders place the guides on the outside of the spine curve while spinning guides should run on the inside of the spine curve (same as fly). By simply replacing the casting eyes with spinning eyes, your rod will now be rotated 180 degrees. What you are most likely to find is that you now have a rod that does not cast as well, but fights the fish better. I don't know anything about Mt Hood Custom Rods and how, or if, they spine their blanks. So your mileage may vary.
