Can I Connect HX Effects to two combo guitar amps' effects send/return?

[ericinmarin]

Hi, all:

 

I'm new to the Forum and apologize if this topic has been covered elsewhere recently (especially with the 2.82 firmware update).

 

I purchased a new Line 6 HX Effects to use in place of my massive pedalboard at gigs that I run in stereo into two clean combo guitar amps.  I presently don't use the guitar amps' effects send/return--just straight into the amp's guitar input

 

I've read on this Forum that, in order to get the best sound from the HX Effects, you need to route the signal through an amp's effects send/return (when not sending the signal into a PA)  I appreciate all the discussion here regarding the 4-cable method for getting the most from the HX Effects when going directly into a single guitar combo amplifier and using the amp's effects send/return (instead of a PA). However, I run my pedalboard into two guitar combo amps, as many of my pedals are stereo.

 

How do I connect the HX Effects to two guitar combo amplifiers to get the most out of it, and is it possible to route it through two guitar amp send/return circuits?  It doesn't seem possible to do this with the  4-cable method or 7-seven cable method using two guitar amplifiers.  Any help is appreciated!  Thanks.
