I don't mean to sound rude, but I think you're getting a bit ahead of yourself. I dumped the bootloader to take a peek, and it appears to not only be locked, but also to have disabled fastboot entirely. Even if you build a recovery, flashing a recovery.img is an almost certain way to end up with a paperweight. We'll need a 2nd init recovery that hijacks the normal boot process, like Safestrap. These require several modifications on /system, and mistakes can easily cripple a device. Without a way to restore the factory rom, it's a fairly dangerous combination, especially for inexperienced devs. Under no circumstance should random users be testing in-progress builds, it'll just end up with bricks all around.
While we're on the topic of bootloaders, at a quick glance ours doesn't seem to be the same codebase as anything with a recent exploit. I'll do some further digging as I can and see if I can match it to an existing open-source project, to help narrow down potential unlock exploits.
