I did some additional testing with USBLoaderGX and WiiU WiiVC mode with HID controllers connected...
I had a suspicion this bug may have something to do with the number of USB devices after my previous findings with the WUPC. I installed my forwarder to Wii U NAND and unplugged all of my USB devices (no WiiU formatted USB storage devices) other than the WiiU GameCube Adapter.
I was able to successfully boot a GameCube game using a NAND installed forwarder without any USB storage devices plugged in approximately 50% of the time. Below is an example of one of my barge of tests.
Oddly, deleting the settings/stats files for USBLoaderGX seems to increase the likelihood of booting a GameCube game to 80%+ (sample size ~10 attempts and it could just be dumb luck!)

Round 1 Reset settings/stats by deleting USBLoaderGX files -> booted
Round 2 No changes -> booted
Round 3 No changes -> black screen of death
Round 4 No changes -> black screen of death
Round 5 No changes -> booted
