After spending some time grinding down the pegs to an appropriate length, I've completely filled the pegbox with the required 8 tuners. Alternating the 90 degree tuners allows for relatively easy access to all of them. I didn't even have to drill any new holes in the pegbox itself - I simply slightly bored out the existing ones to receive the metal tuners. And before you ask, yes, this increases the weight of the scroll side a bit, but hopefully it will still be easily playable.
