Jerry,

The Behringer 802 mixer is inexpensive and will do that for you (plus a 
lot of other stuff)
Feed each receiver's audio into the Line IN jack below the microphone 
jacks.  The PAN control will be used to adjust the amount of blend you 
want.  In addition you will have level controls for each channel as well 
as a single control for the headphone level and another for the main out 
- lots of flexibility.

The downside of the Behringer 802 is that it does not contain a power 
amplifier, but has more than adequate output for headphones - add a 
stereo power amplifier if you need or want to drive speakers.

73,
Don W3FPR.
