If you use the Zone 2 stuff in your 720 you won't be able to get either ARC or Crossover processing for Zone 2. Zone 2 output is 2.0 channels only, and the only processing that happens is Volume control and down-mix of multi-channel sources to 2.0 channel output (if you have Zone 2 Follows Main enabled).
If you want ARC, or Crossover processing without ARC, for this additional set of speakers you will need to hit it with a bigger hammer -- to wit, add a Stereo speaker switch.
The switch would take the L/R speaker output of your 720 and send it either to your normal Home Theater front speakers or to the new pair of speakers you are trying to add. Meanwhile, the other speaker outputs would go directly to your normal speakers (including the Subwoofer) for EITHER use -- no need to switch those. Such switches can be found at places like Monoprice. You can likely even get one that's remote controllable, so you can select which speakers get the output of the 720 as part of doing the other remote control operations for switching between these two setups.
Now, having set that up, let's assume you use only Speaker Profile 1 at the moment -- for your Home Theater. You will continue to use Profile 1 that way, but now you will also set up Profile 2 for when you want to use the new speakers. Specify Profile 2 in ARC as having only L/R front speakers and the Subwoofer, i.e., a 2.1 configuration.
You do this in the setup panel that appears when you are configuring to begin an ARC Measurement pass. The other thing you MUST do is to set Profile 2 in that panel to *NOT* use the Measurements ARC takes for Profile 1. I.e., you want a separate set of mic positions Measured for each Profile in turn.
Start with the speaker switch set to use your normal Home Theater speakers. When you begin your ARC Measurements, ARC will tell you to position the mic in turn to the 5 positions for Profile 1, and will Measure your normal Home Theater speakers. Then it will continue, and tell you to set the mic for the first position for Profile 2. BEFORE starting that 2nd set of sweeps you must change your speaker switch so that the new speakers are used for Front L/R instead of your regular Home Theater speakers. Then say OK to begin mic position #1
for Profile 2, only the two new speakers and Sub will get sweep tones. Continue until the other mic positions are finished for Profile 2.
The result will be an ARC solution containing two Profiles. Profile 1 is for you normal Home Theater speaker setup, and Profile 2 is for your new setup with the two new speakers (and Sub). Those two Profiles are independent of each other -- they will each contain a solution appropriate for the speakers you had active during the respective mic position passes.
Tweak the Targets for those two Profiles to taste if you wish (they can be adjusted separately), then Calculate (which updates the solution for any Target changes you made), and Upload.
Now in the 720 you will have Profile 1 and 2 (or whatever different name you told ARC to assign to them).
Next set up Inputs in the 720 to use the two Profiles.
For example, you might set up an OPPO Input for movies with audio coming in on HDMI. That Input should be set to use your Speaker Profile 1.
Then you might add an OPPO input for music with Stereo content audio coming in on HDMI or on Stereo Analog or whatever. That Input should be set to use your Speaker Profile 2.
When you change between these Inputs you must also change the setting on your new speaker wires switch to match. The choice of with Profile to use has already been made by you in the Input definition, so that happens automatically.
Repeat for your other source devices.
