Hi Matthew,
The Hermes-Lite only attempts to be compatible with openHPSDR protocol 1 for core use. As you have discovered, we have additional extensions that Quisk and SparkSDR use. For example, the 6 bits for C0 is because we have added commands that require a response by using the extra bit. This is documented on the wiki: https://github.com/softerhardware/Hermes-Lite2/wiki/Protocol
I'd be interested in hearing if you think any of the extensions would conflict with core openhpsdr software use.

The major issue is that my plug-in is not correct .I is treating the 7 bit C0 type a a 8 bit number. This will be corrected in the next release. The OpenHPSDR protocol 1 documents are not written in a way that lists the length of the fields.
There should be no issue with Hermes-Lite2 additional 6 bit C0. When they are treated as 7 bit numbers the 7th bit is a zero.
The conflict with C0 18 (0x12) is due to the newest version of the protocol. I let you know if I discover any more conflicts.
Corrected list of "C0 Types": // The "C0 Types" are 7 bit numbers. // Before version 0.4.0 they were in-correctly treated as 8 bit numbers. // 0 0x00 Configuration // 1 0x01 TX NCO Frequency // 2 0x02 RX 1 NCO Frequency // 3 0x03 RX 2 NCO Frequency // 4 0x04 RX 3 NCO Frequency // 5 0x05 RX 4 NCO Frequency // 6 0x06 RX 5 NCO Frequency // 7 0x07 RX 6 NCO Frequency // 8 0x08 RX 7 NCO Frequency // 9 0x09 TX Drive, Anntena Presect, VNA // 10 0x0A RX Pre-amp, IF Gain, PureSignal, Open Drain, TTL, 20db/ADC1 Attn // 11 0x0B ADC[123] Attn, CW Config // 12 0x0C Additional Mercury 1 // 13 0x0D Additional Mercury 2 // 14 0x0E ADC RX Assignment // 15 0x0F CW Configuration 2 // 16 0x10 CW Configuration 3 // 17 0x11 PWM Configuration // 18 0x12 2ND Alex, Firmware Envelope Gain

There is a new version of the OpenHPSDR USB frames over IP protocol. The document for version 1.60 was paced on Github in the past month. The the Hermes-Lite2 "C0 Type" for "RX 8 NCO Frequency" over laps with the new "C0 Type" for "2ND Alex, Firmware Envelope Gain" that was added in version 1.60 of the official protocol. Also in the protocol document the "C0 Types" are defined as 7 bit numbers NOT 6 bit numbers. I am adding the Hermes-Lite2 to my Wireshark plugin "openhpsdr-u". The plug-in uses 7 bit numbers for the "C0 Types" below are the 7 bit numbers for the Hermes-Lite2 addtional "C0 Types"
